Hardfacing Electrodes
CROMA
AWS: SFA
EN ISO CODE:
Croma is a AC/DC (+) type electrode depositing a 16Cr-4Mn weld metal which has work hardening characteristics. The weld metal resists impact abrasion and corrosion. Ideally suited for hardfacing applications to enhance resistance to impact abrasion. Ideal for buffer layers before depositing air hardening deposits. Typical applications include surfacing and building up of austenitic manganese steel components, crusher jaws, crusher hammers, roll crushers, mining machineries, dipper teeth, etc.
