▎Applications and Features

KH-SLB is a co-based hardfacing electrode (equivalent to Stellite 12). Its feature is similar with KH-SLA. The hardness and abrasion resistance of KH-SLB is better than KH-SLA.
It can be machined by carbide cutter.
It is suitable for injection molding screws, high temperature turbine blades, deep drawing mold and bearing.

▎Welding Position

▎Welding Instruction

The dilution rate deteriorates the hardness and corrosion resistance.
Dragging a 90-degree angle or a short arc can reduce the dilution of weld metal.
Preheat and Int. temperature should be 400~500°C. Use slow cooling after welding to prevent cracks.
Dry the electrodes at 200-250°C for 30-60 minutes before use.

▎Applications

It is suitable for injection molding screws, high temperature turbine blades, deep drawing mold and bearing.
