Direct answer: Stainless steel strip cannot be selected by the word “stainless” alone. Buyers should identify the stainless family, exact grade and standard, delivery condition, target properties, dimensions, surface, edge and inspection method. Hengtaifeng reviews listed grades and processing routes order by order; a family name does not guarantee a particular condition or dimension.
Austenitic vs Martensitic Stainless Steel Strip
| Buyer question | Austenitic strip | Martensitic strip |
|---|---|---|
| Listed enquiry examples | SUS301, SUS304, SUS316 | SUS410, SUS420, SUS440C |
| Selection focus | Grade, cold-work condition, formability, surface and corrosion environment | Grade, heat-treatment condition, hardness or property target, surface and finished-part validation |
| Strength request | Define the cold-work or other delivery condition and required tensile test result | Define the applicable heat-treatment condition and required test result |
| Automatic substitution | No. Compare the complete governing standards, product form, chemistry, properties and acceptance criteria. | |
The industry association worldstainless classifies austenitic and martensitic stainless steels as distinct families and describes their different microstructures and general processing characteristics. That family-level guidance does not replace the applicable product standard or purchase specification.
What “High-Tensile Stainless Steel Strip” Should Mean in an RFQ
High-tensile stainless steel strip is not a complete grade. It is a property-led request. State the base grade, condition, tensile-property range, test method, sampling direction and frequency, thickness and width tolerances, and the downstream forming operation. If spring response matters, define the finished-part test or design criterion rather than relying on “high strength” as the acceptance term.
Hardened and Tempered Stainless Strip
Do not assume that austenitic and martensitic grades can use the same hardening route. The requested grade, starting condition, section, target properties, surface and finished-part requirements must be reviewed together. For general carbon and spring-steel procurement, see the separate hardened and tempered steel strip page.
Supply and Processing Review
Applicable operations may include cold rolling, leveling, annealing, heat treatment, precision slitting and cut-to-length processing. Not every operation or delivery condition applies to every grade.
Across the material and processing portfolio, thicknesses may range from approximately 0.01 mm to 10 mm. Selected materials may be evaluated in widths up to approximately 1,000 mm. These figures are not available for every grade and condition. Final dimensions, tolerances and processing feasibility are subject to technical review.
Stainless Strip RFQ Checklist
| Field | What to provide |
|---|---|
| Grade identity | Exact designation, governing standard and edition; attach the drawing or material specification |
| Delivery condition | Annealed, cold-worked, heat-treated or another explicitly defined condition |
| Property acceptance | Tensile, hardness or other range with scale, test method, direction and sampling plan |
| Dimensions | Thickness, width, tolerances, coil ID/OD or cut length |
| Surface and edge | Finish, roughness or appearance limits, burr and edge geometry |
| Application | Forming route, environment, finished-part validation, quantity and destination |
Frequently Asked Questions
What is the difference between austenitic and martensitic stainless steel strip?
They are different stainless-steel families with different microstructures and processing responses. The exact standard, grade, condition and acceptance criteria must control the order.
Is high-tensile stainless steel strip a grade?
No. It describes a requested property or condition. The base grade and acceptance method still need to be defined.
Can every stainless grade be supplied hardened and tempered?
No. Heat-treatment and cold-work routes depend on the exact grade, starting condition, section and target properties.
