摘要：
An exhaust equipment member having an exhaust gas path portion at least partially having a thickness of 5 mm or less is made of a heat-resistant, high-Cr, high-Ni, austenitic cast steel having weight ratios of Cr/Ni of 1.0-1.5 and Mn/S of 5 or more a composition by weight of 0.2-1.0% of C, 2% or less of Si, 2% or less of Mn, 0.04% or less of P, 0.05-0.25% of 5, 20-30% of Cr, and 16-30% of Ni, the balance being substantially Fe and inevitable impurities, with a weight loss by oxidation of 50 mg/cm2 or less when kept in the air at 10100 C. for 200 hours.
