| This is a self-developed new type of material for the rings of PSM 3-Roll Reducing & Sizing Block in the special steel bar rolling line. | |||||||||
◆◇ 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.
High expansion coefficient and good thermal conductivity, more conducive to control
Forming oxide film during rolling process, improving roll wear resistance significantly
Super high strength of the roll core (DCI)
