ISO 6931-2 Stainless Steel Strips For Springs Narrow Strip
ISO 6931-2 Stainless Steel Strips For Springs Narrow Strip
ISO 6931-2, stainless steels for springs, part 2: narrow strip
applies to cold rolled narrow strip, stainless steels covered are classified according to structure into
- austensitic steels
- ferritic steels
- martensitic steels
- precipitation hardening steels
| Austenitic steels | Characteristics | ||
| X5CrNi18-9 | 1.4301 | 304 | these steels are hardend by cold worked processing, to obtain the specified hardness. |
| X10CrNi18-8 | 1.4310 | 301 | |
| X5CrNiMo17-12-2 | 1.4401 | 316 | |
| Ferritic steels | |||
| X6Cr17 | 1.4016 | 430 | this stainless steel is hardend by cold rolling. |
| Martensitic steels | |||
| X20Cr13 | 1.4021 | 420A | Martensitic steels are hardened by heat treatment, more springy than austensitic, ferritic steels. High magnetic permeability in all conditions ( annealed or QT ) |
| X30Cr13 | 1.4028 | 420B | |
| X39Cr13 | 1.4031 | 420 | |
| Precipitation hardening steel | |||
| X7CrNiAl17-7 | 1.4568 |
631 17-7PH |
