Property classes
ISO 898-1 · ISO 3506-1| Class | Rm min. | Yield requirement | Elongation requirement | Hardness | Typical use |
|---|---|---|---|---|---|
| A2-70 | 700 MPa | Rp0.2 min. 450 MPa | 0,4d mm | - | Cold-worked austenitic stainless, typically 304 — outdoor, wet and food service away from chlorides. |
| A4-80 | 800 MPa | Rp0.2 min. 600 MPa | 0,3d mm | - | The strongest 316-type class; marine and chemical service where 70 does not carry the load. |
These values meet the requirements of ISO 3506-1. We supply to these classes and issue the matching mill certificate and third-party test report with your order.
