Abstract
PURPOSE: To provide the heat-resisting steel which has been improved in the high- temperature strength at weld parts without losing the formability thereof and is suitable for the automotive exhaust gas purifying device by particularly restricting the Cr equivalent of a steel containing specified amounts of C, Si, Mn, Ni, Cr and N.
CONSTITUTION: The heat-resisting steel contains not more than 0.05wt% C, 0.2W 1.5wt% Si, not more than 1.5wt% Mn, 0.1W1.0wt% Ni, 10.0W15.0wt% Cr and not more than 0.05wt% N, the balance being essentially Fe and unavoidable impurities, wherein the Cr equivalent defined as Cr+2Si-30C-15N-2Ni-Mn is in the range of 10W13. Further, a total amount of 0.05W0.35wt% Ti and Nb is incorporated into the steel, as required. By thus restricting particularly the Cr equivalent in the said composition, more than 30% martensite phase is formed at the weld parts influenced by heat, so that a two-phase structure consisting of ferrite and martensite is produced and the high-temperature strength of the weld parts is improved. Accoringly, a hot-rolled plate equal in thickness as that of ferrite stainless steel can be produced from said heat-resisting steel.
