KH-SLB
Type of coating: Lime titania type
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

Classification


Application 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

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