Abstract (en)
A martensitic stainless steel of this invention, aimed at achieving excellent corrosion resistance and cold workability and a desirable level of toughness, while keeping the hardness equivalent to that of conventional martensitic stainless steel, which consists essentially of, in % by mass, C: 0.15-0.50%, Si: 0.05% or more and less than 0.20%, Mn: 0.05-2.0%, P: 0.03% or less, S: 0.03% or less, Cu: 0.05-3.0%, Ni:0.05-3.0%, Cr: 13.0-20.0%, Mo: 0.2-4.0%, V: 0.01-1.0%, Al: 0.030% or less, Ti: less than 0.020%, O: 0.020% or less, N: 0.30-0.80%, and the balance of Fe and inevitable impurities.
