ALLOY CAST STEEL ROLL

◆ SUMMARY

They are made of high quality steel melted with electric arc furnace (EAF) and finished with advanced foundry and heat treatment technologies.

Roll barrel is mainly composed of pearlite (or temper sorbite) in the microstructure.

◆ ADVANTAGE

◇ High tensile strength

◇ High wearability

◇ Good toughness

◇ Excellent resistance to fire crack
