For example, the chemical composition of ZG40Cr9Si2 ranges from C 0.35 to 0.50%, Si 2.00 to 3.0%, Cr 8.00 to 10.0%, while the chemical composition of ZG30Cr26Ni5 ranges from C 0.20 to 0.40%, Cr 24.0 i go long 28.0%.

Specifically for some specific heat-resistant steel castings, such as ZG35Cr24Ni7SiN, its chemical composition is designed to improve the oxidation resistance and high temperature strength of the material, in which Cr, Ni, Si and other elements play an important role in improving the oxidation resistance and high temperature strength of the material, and the addition of Re element enhances the creep performance and lasting strength of the material 2.
