Zusammenfassung:An austenitic, stainless steel alloy having a good combination of galling resistance and corrosion resistance is disclosed, containing in weight percent Broad Intermediate Preferred C 0.25 max. 0.02-0.15 0.05-0.12 Mn 4-10 4-8 5-7 Si 2.25-5 2.5-4.5 3-4 Cr 16.5-23 16.5-21 17.5-19 Ni 6-12 6-10 6-9 Mo 0.5-4.0 0.5-2.5 0.75-1.5 N 0.10-0.35 0.10-0.25 0.10-0.20 The balance of the alloy is essentially iron. This alloy has good resistance to formation of deformation-induced martensite as indicated by the alloy's low work-hardening rate, and low magnetic permeability when cold-rolled to a 50% reduction in cross-sectional area.
