Shaanxi Shangyou Stainless Steel Co., Ltd. supplies 301 full hard stainless steel strip for high-strength spring clips, retainers, bands and elastic stamped components. Because full-hard 301 has limited remaining formability compared with softer tempers, the incoming mechanical-property range, bend geometry, edge condition and stamping sequence should be confirmed before production.
| Parameter | Specification / Guidance |

| Typical Thickness | 0.05-1.50 mm reference range |
| Typical Width | 3-400 mm reference range |
| Surface | Specified cold-rolled surface subject to temper route |
| Edge | Slit / deburred / conditioned |
| Critical Requirement | Actual tensile/hardness range should be defined for engineering orders |
| Inspection | Mechanical properties/hardness plus thickness, width and edge checks |
| Production | Made-to-order or regular production depending on size and required property range |
| Parameter | Specification / Guidance |
|---|---|
| Grade / UNS / EN | UNS S30100 / EN 1.4310 |
| Applicable Standards | ASTM A666/A666M for cold-worked austenitic strip; EN 10151 / ISO 6931-2 for spring-strip applications where specified; ASTM A480/A480M general requirements. |
| Inspection Documents | MTC / EN 10204 3.1 when specified; dimensional, surface and hardness reports; PMI available where technically appropriate. |
Full-hard 301 obtains its strength from substantial cold work. This makes it useful for spring and elastic components, but the same cold work reduces ductility. If the final part requires severe drawing or tight-radius forming, the buyer should validate whether full-hard incoming material is appropriate.
For critical spring parts, specify the actual mechanical-property range required by the drawing or standard. Two coils both described commercially as “full hard” may not be interchangeable if thickness, tensile strength, hardness, edge and rolling direction differ.
Choose 301 full hard when high incoming strength and spring response are required and the part geometry can be produced from that condition. Choose a softer 301 temper when additional forming is needed. Choose 316L or another alloy when corrosion performance is more important than maximum cold-worked spring strength.

| Parameter | Specification / Guidance |
|---|---|
| Slitting / Cutting | Precision slitting, cut-to-width and rewinding according to grade, gauge and coil configuration. |
| Edge Processing | As-slit, deburred or conditioned edge where the requested dimensions and application allow. |
| Testing | Dimensional inspection, surface inspection, hardness/mechanical checks as specified; PMI or third-party inspection can be arranged where appropriate. |
| Documentation | MTC / EN 10204 3.1 when specified; dimensional, surface and hardness reports; PMI available where technically appropriate. |
| Packing | Moisture-proof paper or film, edge protection, steel strapping and export pallet/wooden case as required. Coil eye orientation and maximum package weight can be agreed before shipment. |
| Price Basis | Price is determined by grade, thickness, width, temper/hardness, surface, tolerance, edge condition, coil configuration, order quantity, inspection and packing requirements, plus current stainless raw-material/alloy costs. |
| Supply Status | Stock, regular production or made-to-order depending on grade, dimensions, temper, finish and inspection requirements. |
Send drawing + thickness × width + required tensile/hardness range + bend radius + edge/burr + coil ID + quantity. We will review whether full-hard incoming strip is compatible with the forming sequence.
1. What does “full hard” mean for 301 strip?
It indicates a high cold-worked strength condition; the purchase order should still define the required mechanical-property range.
2. Is full-hard 301 stronger than annealed 301?
Yes, cold working substantially increases strength while reducing ductility.
3. Can full-hard 301 be deep drawn?
Deep drawing is generally limited compared with softer conditions; part geometry should be validated.
4. Is full-hard 301 suitable for springs?
Yes, it is a common choice for high-strength spring components when the design matches the material condition.
5. Can it be supplied with deburred edges?
Yes, deburring or edge conditioning can be quoted.
6. Should I specify HRC or HV?
Specify the hardness scale and range required by your drawing or standard; tensile properties may also be needed.
7. Can you slit full-hard 301 to narrow widths?
Yes, but minimum width and edge quality depend on thickness, strength and tooling.
8. Does full hard improve corrosion resistance?
No. Cold work mainly changes mechanical properties; corrosion behavior still depends on grade, environment and surface condition.
9. Can full-hard 301 be welded?
Welding is possible in many cases, but the heat-affected zone changes the cold-worked microstructure and mechanical properties, so the finished part must be engineered accordingly.
10. What data should be on the MTC?
The document should identify heat/lot traceability and the chemistry/mechanical test data required by the governing standard and purchase order.
