CCR (Special)
AWS: SFA
EN ISO CODE:
CCR(SPL) is a semi-basic super heavy coated hardfacing electrode producing a high carbon, high chromium and nickel alloy weld deposit. The weld metal is extremely hard at room temperature and retains its hardness up to 550°C. The weld metal has excellent resistance to high temperature abrasion. Typical applications include hardfacing of blast furnace bells, hoppers, parts in coke chutes, coal handling equipments, etc.
