Abstract (en)
[origin: WO8702388A1] Austenite stainless steel containing, by weight, 0.03% or less C, 2.00% or less Si, 5.0% or less Mn, 0.030% or less S, 16 to 20% Cr, 6 to 13% Ni, 0.15 to 0.28% N, 0.05 to 0.25% Nb, 0.0020% or less B, the balance of Fe and impurity elements and, optionally, 4% or less Mo, 4% or less Cu, and 0.005 to 0.080% Se, and process for its production. This stainless steel has excellent strength, excellent grain boundary resistance, stress-corrosion cracking resistance, and excellent hot workability, thus being useful as strength-providing members for use in various chemical plants, desalination plants, nuclear plants, etc.
