Co-based hardfacing wire HS116 very AWSRCoCr-C 
 Main chemical composition /% 
 C0.7-1.2 Cr30.0-34.0 W12.5-15.5 Si ≤ 1.0 Mn ≤ 0.5 Fe ≤ 1.0 Co margin 
 Surfacing layer hardness HRC :46-50 
 Main characteristics and use: 
 Have high wear resistance and high temperature strength, but the toughness is poor,, phosphoric acid, nitric acid and other working conditions were excellent corrosion resistance. Mainly for copper and aluminum alloy welding heat dies, etc.
