ABSTRACT:
A chromium nickel silicon stainless steel alloy with improved wear resistance consists of, in weight percent, 19 to 22 chromium, 8.5 to 10.5 nickel, 5.25 to 5.75 silicon, 1.7 to 2.0 carbon, 8.0 to 9.0 niobium, 0.3 to 0.5 titanium and the balance iron plus impurities. The addition of titanium and increased amounts of niobium and silicon alter the microstructure of the stainless steel to form a duplex austenitic/ferritic microstructure which undergoes secondary hardening due to the formation of an iron silicon intermetallic phase.
