HS113 cobalt welding wire 
 Main chemical composition /% 
 C2.5-3.3 Mn ≤ 1.0 Si0.4-2.0 Cr27-33 W15-19 Fe ≤ 2.0 Co margin 
 Surfacing layer hardness HRC :55-60 
 Main characteristics and use: 
 HS113 cobalt-based hardfacing wire, high hardness, wear resistance is very good, but the impact of the poor tend to crack when welding, and has good corrosion resistance, heat resistance, wear resistance, is still at about 650 ℃ maintain these properties. Mainly used for rock bit bearings, boilers, rotary blades, grinder blade, screw feeder so cladding
