LOW CARBON MARTENSITIC STAINLESS STEEL EXCELLING IN HARDENABILITY AND RUST RESISTANCE

摘要

PURPOSE:To improve hardenability and rust resistance by reducing the S content of the low carbon martensitic stainless steel to the utmost, reducing the Mn content and adding Cu, and further adding specific amounts of N. CONSTITUTION:As the steel for a motorcycle disc brake, etc., having superior rust resistance as well as hardenability, the martensitic stainless steel containing 0.04-0.10% C, 0.03-0.07% N, 0.5% Si, 0.5-1.2% Mn, 0.01% S, 10-15% Cr, 0.6% Ni, and 0.3-1.0% Cu is used. The S content is reduced to the utmost in order to decrease the formation of MnS causing deterioration in rust resis tance, and the formation of CuS by Cu controls the formation of MnS to improve rust resistance. Moreover, by increasing the N content to increase needle-like precipitates of beta-Cr2N, hardening solutionization can be accelerated.
