BYR8 HIGH THERMAL FATIGUE RESISTANCE HOT ROLLING WR(NON FERROUS)

properties and characteristics

• High hardness
• High tempering temperature
• High thermal fatigue resistance

BYR8 WR is a forged steel semi-high-speed roll for non-ferrous hot rolling, which is developed by optimizing the alloy content of Si, Mo, V, etc. on the basis of Cr5. The roll has high hardness, high tempering temperature, and high fatigue resistance characteristics, which benefits from the combination with a reasonable heat treatment process.

Smelting process : smelting + LF + VD + ESR
