Abstract (en)

A new austenitic stainless steel with the following composition by weight is described: 0.03 % < carbon < 0.07 % 7.0 % < manganese< 8.5 % 0.3 % < silicon 0.7 % sulphur ‰¤ 0.030 % phosphorus ‰¤ 0.045 % 16.5 % < chromium < 18.0 % 3.5 % < nickel < 4.5 % 0.1 % < molybdenum < 0.5 % 1.0 % < copper < 3.0 % 0.1 % < nitrogen < 0.3 % the difference consisting in iron and common process impurities. The steel thus obtained has an optimum combination of corrosion resistance, deformability and work-hardening properties, which make it suitable as a substitute for normal steel type 1.4301 in various specific applications.
