D802 cobalt-based electrodes 
 Model: GB / T EDCoCr-A-03 rather: AWS ECoCr-A JIS DF-CoCrA 
 Description: cobalt chromium tungsten alloy cobalt-based hardfacing welding rod core, the use of DCRP, deposited metal work at 650 ℃ can maintain good wear resistance and corrosion resistance. 
 Use: about 650 ℃ work can still maintain good wear resistance and corrosion resistance of the occasion, or to withstand shocks and hot and cold cross the site, such as the welding temperature and high pressure valves and thermal cutting edge and so on. 
 Surfacing hardness HRC: ≥ 40
