Hardfacing Electrodes
ES 250 KPR / EN 14700: E Fe 9
Description
ES 250 KPR is indicated for coating of components subject to high impact with abrasion. The work man ship can be done in ferritin steel, as well in austenitic manganese steel and Manganese steel junction can be welded. Its main applications are in the cement industry, sugar industry, a line of rails and steel works in which work pieces are regenerated, as well as jaw-breaker, breaker pounding sidewalks and arms, alligators and cross pieces, roll axis, pushers conveyor belt and Clover cylinder engines.
