Use & Application
12%CrMoV steels are used for critical heat and creep resisting service up to at least 550ºC. The high chromium level confers superior steam and fireside corrosion performance compared with 2-9%CrMo creep-resisting steels. Used in cast and wrought form for high pressure steam piping and headers, heat exchangers and turbine components, particularly in the power generation industry and sometimes in petrochemical applications.
Alloy type
12%Cr creep resisting steel also with nominally 1%Mo-0.5%W-0.3%V. The matching base material is generically called X20.
In the PWHT condition the microstructure consists of tempered martensite.
