| European Steel Designation | AISI Nearest Fit | Service Properties | Applications |
|---|---|---|---|
| 1.4568 X7 Cr Ni Al 17-7 |
631 | Improved corrosion resistance when compared with martensitic steels although less so than the base grade austenitic stainless steel 1.4301 (AISI 304); good formability in the soft condition; good fatigue life after hardening; high cost heat treatment from the solution annealed condition; low cost heat treatment from the cold rolled condition; high strength and stress relaxation properties. | springs, pressings, diaphragms, encapsulated bellows, flexures, fluid seal springs |
| 1.4532 X8 Cr Ni Mo Al 15-7-2 |
632 | As above although slightly higher mechanical properties can be achieved following heat treatment; | applications are as above |
