EFeMn-A Welding Rods for Hardfacing (CHR256A)
EFeMn-A welding rod is used for hardfacing percussive and abraded parts of crusher machines, excavators, bulldozers, steel rail and so on. The deposited metal is one kind of austenitic high manganese steel so it would be harder, tougher and more abrasion-resisting after processing.
Type of Covering: Low hydrogen, potassium
Welding Position: F, H, HF, OH, V
Type of Current: DCEP or AC
