▎Applications and Features

KH-SLC is a co-based hardfacing electrode (equivalent to Stellite 1). Its feature is similar with KH-SLA and KH-SLB. However, the impact and corrosion resistance might be lower.
It can be deposited on carbon steel, low alloy steel, stainless steel and Ni-based alloy.
It is suitable for anti-corrosion, anti-oxidation and anti-abrasion conditions, such as agitator bearings, high temperature sinters, molds and blades.

▎Welding Position

▎Welding Instruction

Preheat temperature should be 500°C and slow cooling is required to prevent cracks.
Remove the sharp angle and scale before welding. Dragging a 90-dregee angle or short arc can reduce the dilution of the weld metal.
For room temperature condition, use KMS-309Mo as buffer layer; and, for high temperature condition, use KNi-70B instead.
Dry the electrodes at 200-250°C for 30-60 minutes before use.

▎Applications

It is suitable for anti-corrosion, anti-oxidation and anti-abrasion conditions, such as agitator bearings, high temperature sinters, molds and blades.
