Abstract

A precipitation hardening martensitic stainless steel is provided with excellent mechanical property and corrosion resistance and contains, by mass, 0.1% or less of C; 0.1% or less of N; 10.0% ~ 15.0% of Cr; 10.0% ~ 15.0% of Ni; 0.5% ~ 2.5% of Mo; 1.0% ~ 3.0% of Al; 1.0% or less of Si; 1.0% or less of Mn, and the rest is Fe and inevitable impurities. A steam turbine long blade (10) is made of the precipitation hardening martensitic stainless steel.
