The RM 1 coated electrode is made of H0Cr21Ni10 wire core and is alloyed chromium and nickel simultaneously through coating material and wire core and some rare earth oxides are added in coating material. The electrode has been verified to be satisfied the operation requirements of practical production.展开更多
