Abstract

A steel having high creep and stress-rupture properties at elevated temperatures comprises: .Fe.-.-.-.balance .Cr.-.-.-.0.4-7.5% .Mo.-.-.-.0.4-4.0% .C.-.-.-.0.05-0.4% .Mn.-.-.-.0.1-1.5% .Nb.-.-.-.0.1-1.0% .Ti.-.-.-.0-1.4% .Ni.-.-.-.0-4.0% It may also contain as impurities:- .Up to.0.1% B .Up to.0.02% N .Up to.0.2% Al .Up to.1.5% Si .Up to.0.03% P .Up to.0.03% S After hot working alloys of the invention may be heated to 1800-2200 DEG F., air cooled or quenched to 1300-0 DEG F. and then aged or tempered at 1100-1400 DEG F. for 0.5-24 hours. Such steels may be used for steam power plant components, high pressure vessels for use at high temperatures, and high temperature heat exchangers.
