 Main characteristics and use: 
 HS111 is a cobalt-based welding wire welding Co-Cr-W alloy was the lowest in the C and W, the best kind of toughness. Can withstand the impact of hot and cold conditions, the tendency of cracks is small, has good corrosion resistance, heat resistance and wear resistance. Mainly used when working at high temperatures required to maintain good wear resistance and corrosion resistance, such as high temperature, high pressure valves, hot shear blades, hot forging die, etc.
