D547Mo valve welding electrodes Model: EDCrNi-B-15 surfacing hardness HRC: ≥ 37 
 Description: The chrome-nickel alloy steel valves welding electrodes, the use of DCRP, has a good high-temperature abrasion resistance, erosion resistance and other properties, have high hot hardness, good thermal stability and thermal fatigue, bulk strengthening effect of weld metal significant aging, aging time increased, hardness and resistance to abrasion performance further improved. 
 Uses: Used to work below 600 ℃ high pressure valve sealing surface of the surfacing.
