Temper rolled Stainless Spring Steel W.-Nr. 1.4310 – X10CrNi 18-8 – AISI 301
Composition: C: 0,05-0,15%, Si: max. 2,00%, Mn: max. 2,00%, P: max. 0,045%, S:
max. 0,015%, Cr: 16-19%, Ni: 6-9,5%, Mo: max. 0,80% Condition: temper rolled,
surface 2H, wave height max. 1,0 mm, cut edges.
The alloy 1.4310 (AISI 301) has a good corrosion resistance due to a content of
17% Chromium and 7% Nickel. A high tensile strength is obtained by cold rolling.
Compared to alloy 1.4301 (AISI 304) a much higher tensile strength of more than
2000 N/mm² can be reached. Because of this, the alloy 1.4310 is suitable for stainless
feeler gage stock, precision foils, stainless springs and parts of higher strength.
