Abstract (en)
[origin: EP0638658A1] Martensitic stainless steel including: a - from 0.5 to 0.85 % by weight of carbon + nitrogen b - from 0.15 to 0.24 % by weight of nitrogen c - from 0 to 0.50 % by weight of silicon d - from 0 to 0.70 % by weight of manganese e - from 0 to 0.50 % by weight of nickel f - from 14 to 17 % by weight of chromium g - from 1 to 2.5 % by weight of molybdenum h - from 0.10 to 0.70 % by weight of vanadium, the remaining fraction consisting of iron and of residues and the respective contents of each of these elements being determined so as to restrict the residual austenite content to a value lower than 10 % by volume.
