Grade: YLH40.5 density :13.3-13.6 Flexural strength: 2540 Hardness: 82 Uses: general model for the production of screws and stainless steel screws mold. Grade: YLH40.5 density :13.3-13.6 Flexural strength: 2540 Hardness: 82 Uses: general model for the production of screws and stainless steel screws mold. Carbide combines the advantages of tungsten and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, easy machining, and has features such as transpiration cooling, because having a tungsten high hardness, high melting point, anti-adhesion characteristics, are often used to make a certain wear resistance, high temperature welding, welding electrode.
