AUSTENITIC STAINLESS STEEL EXCELLENT IN HIGH TEMPERATURE CORROSION CHARACTERISTIC AND TOUGHNESS AFTER AGING

摘要

PURPOSE: To produce an austenitic stainless steel having superior high temp. corrosion characteristics and toughness after aging at the time of use in a waste incineration environment, etc. ;CONSTITUTION: This steel has a composition consisting of, by weight, 0.01-0.15% C, 0.05-0.35% Si, 0.3-2.0% Mn, 18-25% Cr, 17-50% Ni, 0.5-3.0% Mo, 0.5-6.0% Al, 0.03-0.3% Ti, 0.05-0.6% Nb, 0.003-0.01% B, 0.02-0.3% N, and the balance Fe with inevitable impurities and containing, if necessary, either or both of 0.0005-0.015% Ca and one or more kinds among 0.001-0.10% Y, 0.001-0.10% La, and 0.001-0.10% Ce.;COPYRIGHT: (C)1995,JPO
