The elemental composition and microstructure of ZGCr5Mo and ZGCr9Mo for high temperature valve were introduced. The mechanisms of high temperature resistance, anti-sulfurization and anti-H corrosion of Cr5Mo and Cr9Mo were described. The technical difficulties in manufacturing ZGCr5Mo were introduced. The chemical composition control of ZGCr5Mo And heat treatment process methods and other key technologies for the correct selection of ZGCr5Mo provides a theoretical basis
