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.
Temper rolled Stainless Spring Steel
Annealed Stainless Steel
W.-Nr. 1.4404 – X3CrNiMo 17-12-2 – AISI 316L
Composition: C: max. 0.03%, Si: max. 2,00%, Mn: max. 2,00%, P: max. 0,045%, S:
max. 0,015%, Cr: 16-19%, Ni: 10-12%, Mo: 2.0-2.5% Condition: in temper rolled
condition surface 2H, flatness according to EN 9445, cut edges In annealed condition
surface 2B or 2R, flatness according to EN 9445, cut edges.
The alloy 1.4404 (AISI 316L) has a very good corrosion resistance due to a content
of 2.0 to 2.5% and a heightened content of more than 10% Nickel. It is suitable for
many applications in the food industry and also for the environmental and medical
