Cr25Ni20 Heat Resistant Cast Steel HK Preheater Panel Fit Cement Plant
Cr25Ni20 ASTM A297 HK Preheater panel for Cement Plant EB3019
The alloy steel with high strength and good chemical stability at high temperature.
It consists of two classes: anti-oxidizing steel (or high temperature non-peeling steel) and hot steel.
Oxidation resistant steel generally requires good chemical stability, but the load is low.
Hot steel requires high temperature strength and corresponding oxidation resistance.
