Description

Properties: - austenitic CrNi-steel with lowered Cr and Ni content, thus in case of cold forming occurs strongly hardening - sufficient corrosion resistance paired with high strength Application: - in cases there is demanded sufficient corrosion resistance paired with high strength - beater bar and sheets for automobiles - preferential application as wire or strip for stainless springs up to an application temperature of 300°C - above 300°C reduction of cold hardening
