  • Austenitic Stainless Steel Alloy
    Publication number: 20150337419
    Abstract: An austenitic stainless steel alloy is provided that includes 0.7-1.2 wt % of N, 10-25 wt % of Ni, 26-34 wt % of Cr, 0.1-1.0 wt % of Nb, 0.1-1.0 wt % of V, and a balance of Fe and incidental impurities.

  • Corrosion resistant austenitic stainless steel with improved galling resistance
    Patent number: 5340534
    Abstract: An austenitic, stainless steel alloy having a good combination of galling resistance and corrosion resistance is disclosed containing in weight percent about:______________________________________ Broad Intermediate Preferred ______________________________________ C 0.25 max. 0.02-0.15 0.05-0.12 Mn 3-10 4-8 5-7 Si 2.25-5 2.5-4.5 3-4 Cr 15-23 16.5-21 17.5-19 Ni 2-12 4-10 6-9 Mo 0.5-4.0 0.5-2.5 0.75-1.5 N 0.35 max. 0.05-0.25 0.10-0.20 ______________________________________and the balance of the alloy is essentially iron. This alloy also 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.
