Beschreibung
Zusammenfassung:	Material comprises an alloy containing (in wt.%) 0.01-0.25 C, 0.35-2.5 Si, 0.4-4.3 Mn, 16.0-28.0 Cr, 15.0-36.0 Ni, 0.01-0.29 N and a balance of Fe, with the proviso that the Ni content of the alloy fulfills the following equation: Ni at least Cr + 1.5 x Si -0.12 x Mn - 18 x N - 30 x C - 6. The material has a hardness formed by cold forming of at least 230 HB. An Independent claim is also included for a process for the production of the material
