SUS 201 vs 304 vs 316 Stainless Steel for Commercial Kitchen Equipment: B2B Material Selection Guide
For importers, distributors, wholesalers, OEM buyers and commercial kitchen project teams, choosing between SUS201, SUS304 and SUS316 stainless steel is not simply a matter of selecting the highest grade. The correct material depends on the product, the component, the operating environment, the required corrosion-resistance margin, the actual thickness, the buyer's market positioning and the approved project specification.
Based on SENFON's current export-order experience, SUS201 and SUS304 are the two most common material choices across our commercial kitchen equipment business. SUS316 is available across SENFON's stainless steel equipment range when required, but it is more often driven by a defined project specification than by a general distributor order.
Buyers reviewing the complete equipment range can also explore SENFON commercial stainless steel kitchen equipment.
SUS201 vs SUS304 vs SUS316: B2B Selection Matrix
Material comparison is most useful when it is connected to the buyer's real purchasing task. Grade, environment, thickness, component structure and price positioning should be reviewed together rather than separately.
| Buying Factor | SUS201 | SUS304 | SUS316 |
|---|---|---|---|
| General B2B positioning | Cost-conscious commercial option | Mainstream commercial-kitchen option | Higher-specification or project-driven option |
| Typical SENFON order pattern | Common in distributor and general market orders | Common across sinks, worktables, cabinets and projects | More often specified for defined projects or demanding applications |
| Relative corrosion-resistance margin | Lower than SUS304 in a general comparison | Strong general-purpose margin for many commercial-kitchen applications | Higher margin, especially relevant in more aggressive conditions |
| Dry or moderately humid indoor use | Often considered when the application and cleaning conditions allow | Commonly suitable | Normally unnecessary unless the specification requires it |
| Frequent washing / wet service | Requires more careful application review | Common choice | Relevant when a higher corrosion-resistance margin is required |
| Salt / chloride or more aggressive exposure | Usually reviewed cautiously | Application-specific | More relevant because molybdenum improves resistance in chloride-containing environments |
| Relative material cost | Generally lower | Generally higher than SUS201 | Generally higher than SUS304 |
| Buyer should confirm | Application, component, actual thickness and target price level | Component, actual thickness, cleaning conditions and documentation | Project specification, component, material standard and operating environment |
The cost order is generally SUS201 < SUS304 < SUS316 when comparable product specifications are being discussed. Actual quotations still depend on current steel pricing, thickness, product structure, component mix and order requirements.
When Does SUS201 Make Sense for Commercial Kitchen Equipment?
SUS201 belongs to the 200-series austenitic stainless steels. Compared with standard chromium-nickel grades such as SUS304, part of the nickel is replaced by manganese and nitrogen. This helps create a lower-cost material option while retaining useful strength, formability and corrosion resistance for suitable applications.
For commercial kitchen equipment, SUS201 can be a practical choice when the product is used in a relatively mild indoor environment and the buyer's market places strong importance on price competitiveness. Dry environments and normal indoor humidity are generally easier applications than continuously wet, highly saline or chemically aggressive conditions.
In SENFON's export business, SUS201 is common in distributor and wholesale orders for products such as worktables, cabinets, shelving, carts and other stainless steel equipment. It is also used for selected sink-related structures when the buyer's approved specification requires it.
The important point is that SUS201 should be selected because it fits the buyer's actual application and market position, not simply because it has the lowest initial material cost.
Why Is SUS304 So Common in Commercial Kitchen Equipment?
SUS304 is one of the most widely used austenitic stainless steels for commercial kitchen and food-equipment applications. It offers a strong balance of corrosion resistance, fabrication performance, weldability and availability, which makes it suitable for a broad range of commercial-kitchen products.
In SENFON's current orders, SUS304 is especially common for commercial sinks and sink bowls. It is also widely selected for worktables, cabinets, shelving, trolleys and project-based equipment where regular cleaning, wet service, hygiene requirements or repeatable specifications are important.
Project buyers for hotels, schools, hospitals, central kitchens and other institutional applications often specify SUS304, but this should be treated as a project-specific purchasing pattern rather than a universal rule for every facility.

How Should Buyers Understand “18/8” and SUS304 Chemistry?
SUS304 is often described commercially as an “18/8” stainless steel because chromium and nickel are key alloying elements in this grade family. However, professional B2B purchasing should not rely on the “18/8” label alone because exact chemical-composition limits depend on the applicable material standard.
As one real SENFON material example, a recent SUS304 cold-rolled 2B mill certificate supplied under JIS G4305:2021 specified nickel at 8.00–10.50% and chromium at 18.00–20.00%. The tested coils listed on that certificate were within the specified limits.
This is why a buyer who requires a specific standard should ask for the agreed grade, applicable standard and batch documentation rather than relying only on the word “304” in a quotation.
When Is SUS316 or 316L Actually Necessary?
SUS316 should not be treated as the automatic answer for every order simply because it is positioned above SUS304 in corrosion resistance. It becomes more relevant when the actual operating environment or the project specification requires a higher corrosion-resistance margin.
One important difference is the addition of molybdenum. This improves resistance in chloride-containing and other more demanding environments. Salt exposure, aggressive cleaning chemistry and other corrosive conditions therefore deserve closer material review.
A coastal location by itself does not automatically mean that every product must use SUS316. The equipment position, exposure level, cleaning method, product design and the buyer's project specification still need to be considered.
SENFON can manufacture its stainless steel equipment categories in SUS316 when required by the approved order specification. In practice, 316/316L requirements are more often initiated by experienced project buyers who already have a defined engineering or procurement specification.
As a current material-document example, one 316L cold-rolled 2B mill certificate supplied for SENFON sourcing references ASTM A240/A240M-23 and an EN 10204 3.1 inspection certificate, with specified ranges including nickel, chromium and molybdenum.
What About SUS430?
SUS430 should not be understood simply as a “lower version” of SUS201 or SUS304. It belongs to the ferritic stainless steel family and is used in selected commercial food-equipment and appliance applications.
SENFON can produce equipment according to SUS430 requirements when that material is established in the buyer's local product range or purchasing specification. In some sourcing periods, the price difference between SUS430 and SUS201 can be relatively small. When the buyer does not have a fixed SUS430 requirement, SENFON may therefore discuss SUS201 as another option according to the product and application.
This should not be treated as a permanent price rule. Stainless steel prices change with mill supply and market conditions, so the final comparison should be made when the quotation is prepared.
Does Every Component Need the Same Stainless Steel Grade?
No. In B2B commercial kitchen equipment sourcing, the material can be specified by component when the product design and buyer requirement allow it.
SENFON can support component-level material combinations according to the approved specification. Examples include:
- SUS304 sink bowl + SUS304 worktop + SUS201 undershelf and legs
- SUS304 sink top and bowl + SUS201 cabinet body
- Full SUS201 construction where the product and market requirement allow it
- Full SUS304 construction
- Full SUS316 construction when required by the project specification
Material Grade and Actual Thickness Are Different Specifications
Stainless steel grade and stainless steel thickness are two different purchasing variables. A thicker SUS201 product is not automatically equivalent to a thinner SUS304 product, and a higher stainless steel grade does not automatically mean a heavier or stronger finished product.
Based on SENFON's current distributor-order experience, 1.0 mm is a frequently selected thickness level for SUS201 products. For SUS304, 1.0 mm and 1.2 mm are common choices in many orders. More price-sensitive markets may request 0.8 mm, while project buyers can specify 1.5 mm, 2.0 mm or other thicknesses where the product structure requires them.
These are SENFON order patterns, not universal thickness standards. The correct thickness depends on the product component, dimensions, structure, reinforcement, target positioning and approved drawing.
This distinction also matters when comparing supplier quotations. Two quotations may both say “SUS201 1.0 mm” or “SUS304 1.0 mm,” while the actual component thickness, tube specification, reinforcement, fabrication structure and packing method can still be different.
How Can B2B Buyers Verify Stainless Steel Material?
A quotation label alone does not verify the material grade. When grade confirmation matters, buyers should connect the written specification with appropriate material documentation and, where necessary, inspection.
Depending on the order and agreed requirement, SENFON can provide or coordinate material-related evidence such as:
- LFGB test reports for selected SUS201 and SUS304 stainless steel samples
- Mill material certificates for applicable stainless steel batches
- Batch chemical-composition documentation from the supplying steel mill
- XRF / PMI or third-party material verification when required and agreed
SENFON's current LFGB reports for selected SUS201 and SUS304 stainless steel samples include sensory examination and extractable-heavy-metals testing. The scope of any report should be read according to the tested sample and document itself rather than automatically applied to every product or order.
Buyers can review more information on SENFON's factory and certifications page.
Common Material-Specification Mistakes in B2B Sourcing
Many sourcing disputes do not come from the material name itself. They come from incomplete specifications or from comparing quotations that do not describe the same finished product.
- Writing only “stainless steel” without identifying the grade
- Writing only “SUS304” without stating which components must use SUS304
- Comparing quotations without confirming the actual thickness
- Assuming a higher grade is automatically necessary for every application
- Assuming one test report automatically represents every product and every production batch
- Comparing unit prices without checking tube specification, reinforcement, structure and packing
- Using a grade name in the quotation without defining the applicable material standard when the project requires one
This is especially important when two suppliers appear to quote the same “SUS201 1.0 mm” or “SUS304 1.0 mm” product. The buyer should confirm what the written specification actually means before treating the prices as directly comparable.
How Should Buyers Choose by Operating Environment?
A useful material decision starts with the actual environment rather than with a fixed rule. The following logic can help buyers organize the discussion with a supplier:
| Operating Condition | Material Discussion |
|---|---|
| Dry indoor equipment / mild service conditions | SUS201 may be practical where the buyer's specification and target market allow it |
| General commercial kitchen / regular cleaning | SUS304 is a common starting point for discussion |
| Sink bowls / wet washing stations | SUS304 is common in SENFON orders; final grade depends on buyer specification |
| Institutional or project procurement | SUS304 is frequently specified; documentation and component requirements should be confirmed |
| Higher chloride / salt / aggressive chemical exposure | Review SUS316 / 316L when the environment or project specification requires a higher corrosion-resistance margin |
These are selection principles, not legal requirements for any country or city. The buyer's project specification and actual operating conditions remain the final reference.
How Should a B2B Material Specification Be Written?
To obtain a useful quotation, buyers should provide enough information for the supplier to identify the actual product rather than guess from a short description.
| RFQ Item | What the Buyer Should Provide |
|---|---|
| Product | Product name plus a reference photo, drawing or existing specification |
| Dimensions | Length × depth / width × height and important component dimensions |
| Material grade | SUS201 / SUS304 / SUS316 / SUS430, or material by component |
| Actual thickness | Required thickness by relevant component |
| Quantity | Quantity by model and size |
| Trade term | For example EXW or FOB Qingdao |
| Special requirements | Component materials, backsplash, reinforcement, accessories, packing, applicable standard or required documentation |
A photo or drawing is especially useful because a description such as “1200 mm sink” or “1200 mm worktable” does not define the complete structure. The product may have one or two bowls, two or three tiers, a backsplash or a flat top, or other structural differences that affect the quotation.
Technical Reference Note

These external technical references explain general material characteristics; SENFON order specifications remain based on the buyer's approved product, component, thickness, material requirement and applicable documents.
SUS201 vs SUS304 vs SUS316 FAQ
Is SUS201 suitable for commercial kitchen equipment?
Yes, for suitable applications. SUS201 is commonly used in commercial equipment where the operating environment, cleaning conditions and buyer's market positioning allow it. It generally offers a lower corrosion-resistance margin than SUS304, so the application should be considered before the grade is confirmed.
Is SUS304 always required for a commercial kitchen?
No. SUS304 is a very common commercial-kitchen material, but the correct grade depends on the product, environment, buyer specification and target market. Some orders use SUS201, SUS430 or mixed materials by component.
When should a buyer consider SUS316?
SUS316 or 316L is more relevant when the project specification or operating environment requires a higher corrosion-resistance margin, particularly where chloride or more aggressive exposure is a concern.
Can one product use different stainless steel grades for different components?
Yes. SENFON can manufacture approved mixed-material configurations, such as an SUS304 sink bowl and worktop combined with SUS201 structural components.
Is stainless steel grade enough to compare two quotations?
No. Buyers should also compare actual thickness, component specification, tube structure, reinforcement, fabrication, packing and applicable documentation.
Can SENFON manufacture equipment in SUS316?
Yes. SENFON can manufacture its stainless steel equipment categories in SUS316 when the buyer's approved specification requires it.
