STAINLESS STEEL FOIL AND CATALYST CARRIER FOR EXHAUST EMISSION CONTROL SYSTEM USING SAID FOIL

摘要

A stainless steel foil having high strength at high temperatures, excellent oxidation resistance at high temperatures, and excellent resistance to salt corrosion is provided. A catalyst carrier for an exhaust emission control system that uses the foil is also provided. Specifically, the stainless steel foil is characterized by containing, by mass%, not more than 0.05% C, not more than 2.0% Si, not more than 1.0% Mn, not more than 0.003% S, not more than 0.05% P, over 15.0% but less than 25.0% Cr, not more than 0.30% Ni, 3.0 to 10.0% Al, 0.03 to 1.0% Cu, not more than 0.10% N, not more than 0.02% Ti, not more than 0.02% Nb, not more than 0.02% Ta, 0.005 to 0.20% Zr, 0.03 to 0.20% REM, excluding Ce, not more than 0.02% Ce, and 2.0 to 6.0% Mo and/or W in total, with the remainder comprising Fe and unavoidable impurities.
