HiCr Steel is characterized by excellent fire crack resistance and very good oxidation behaviour at rolling temperature. Very good wear resistance and constant material properties throughout the shell layer.
HiCr Steel is manufactured by horizontal spin casting. No retained Austenite and the right structure and properties are obtained through the chemical composition, high temperature quenching and tempering cycles.
