Abstract

PURPOSE: To obtain a heat resistant steel superior to 18-8 stainless steel in both corrosion resistance and strength at high temp. by using N in place of Ni for maintaining austenite phase when the amount of Cr is increased and by combinedly adding Al and Mg.
CONSTITUTION: This steel consists of 0.01W0.20% C, ≤3%, Si, ≤10% Mn, 20W 35% Cr, 10W45% Ni, 0.04W0.25% N, 0.01W0.5% Al, 0.001W0.05% Mg and the balance Fe with inevitable impurities. It may further contain 0.01W1.0% in total of one or more among 0.01W0.5% Ti, 0.01W1.0% Nb and 0.01W1.0% V, and/or 0.001W0.03% B and/or 0.005W0.30% Zr. The lower limit or more of N is required to produce an effect of improving the strength at high temp., yet more than the upper limit of N does not enhance the effect and exerts unfavorable influence on the toughness after aging. The lower limit or more of Al is required to produce an effect of increasing the strength, ductility and toughness at high temp., yet when the Al content exceeds the upper limit, the effect is not improved furthermore. Mg improves the ductility and toughness, yet excess Mg deteriorates the workability.
