Hardfacing Electrodes
ES 650 / 14700: E Fe 8
Description
ES 650 is indicated for hard coatings subjected to abrasion, combined with impact. The main applications are in the tool industry, mining and sugarcane industry, as well as work in hot and cold environments. The deposit is a martensitic alloy suitable for pressure and impact situations. Machining the weld metal by grinding.
