发明名称 NONMAGNETIC STEEL FOR USE AT VERY LOW TEMPERATURE
摘要 PURPOSE:To obtain a nonmagnetic steel having high strength and toughness and maintaining the nonmagnetism even in a very low temp. range of <=20K by adding specified amounts of Ni, Cr, Mn, Ti and Mo to Fe and regulating the amounts of elements as trace impurities to a specified value or below each. CONSTITUTION:The composition of a nonmagnetic steel for use at a very low temp. is composed of, by weight, 23-30% Ni, 13-16% Cr, 3-15% Mn, 1.5-3% Ti, 1-3% Mo and the balance Fe with elements such as <=0.02% C, <=0.005% P, <=0.005% S, <=0.2% Si and <=0.002% B as inevitable impurities. The composition may further contain <=0.5% Al and <=0.5% V.
