NONMAGNETIC RUST-PROOF STEEL AND ARTICLE MADE THEREOF Russian patent published in 2016 - IPC C22C38/58 C22C38/44

Abstract RU 2573161 C1

FIELD: metallurgy.

SUBSTANCE: proposed composition contains the following substances, in wt %: carbon ≤0.03, manganese 1.0-2.0, chromium 14.0-18.0, nickel 8.5-14.5, nitrogen 0.06-0.35, cerium 0.001-0.05, silicon 2.0-4.5, molybdenum 2.5-4.5, iron and unavoidable impurities making the rest. The following ratios are to be held: (Cr+0.75Si+Mo)/(2Ni+0.5Mn+40(N+C)) = 0.35-1.30.

EFFECT: high rust-proof ability, acceptable physical and mechanical properties.
