▎Welding Consumables – Hardfacing

Stick Electrode

KH-SLC

KH-SLC is a co-based hardfacing electrode (equivalent to Stellite 1).

KH-SLB

KH-SLB is a co-based hardfacing electrode (equivalent to Stellite 12).

KH-SLA

KH-SLA is a co-based hardfacing electrode (equivalent to Stellite 6) and provides corrosion and oxidation resistance. It can be applied in service temperature up to 650°C. It possesses low stress abrasion resistance.

KH-13MN

Weld metal is an austenite structure with 13%Mn-4%Ni and provides excellent crack resistance.

KH-13M

Weld metal remains a stable austenite structure even with air or water cooling after welding.

KH-W
