Abstract

PURPOSE: To provide both superior high temp. corrosion resistance and high temp. oxidation resistance to an alloy steel as well as to maintain the superior high temp. strength by specifying the ratio of C, Si, Mn, Cr, Co, Ni, Ti, N and Mo in the alloy steel compsn.
CONSTITUTION: The alloy steel compsn. consists of, by wt., C 0.01W0.6%, Si 0.1W3%, Mn 0.05W2%, Cr 28W38%, Co 1.5W7%, Ni 21W32%, N 0.01W0.5%, Mo 1W5%, and the balance Fe and inevitable impurities. Since this alloy steel has supeior high temp. strength, high temp. corrosion resistance and high temp. oxidation resistance, it shows superior performance when applied to members such as a sked rail of a heating furnace used under severe conditions such as a hot corrosive atmosphere or a hot oxidizing atmosphere.
