| Angle steel is a kind of carbon structural steel used in construction and engineering. It has good weldability and mechanical strength, it’s widely used in various building structures and engineering structures. The good wear resistance of high-speed steel rolls not only ensure the quality of rolling steel,but also improve the rolling capacity for customers. | |||||||||
◆◇ Unique Features
High V, W, Cr, Mo, Nb and other alloy elements. Carbide types: MC and M2C with high hardness and good abrasion resistance.
Excellet thermal stability, high hardness and good wear resistance.
