- 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 Instruction |

|
(1) The dilution rate deteriorates the hardness and corrosion resistance. (2) Dragging a 90-degree angle or a short arc can reduce the dilution of weld metal. (3) Preheat and Int. temperature should be 400~500°C. Use slow cooling after welding to prevent cracks. (4) Dry the electrodes at 200-250°C for 30-60 minutes before use. |
