Application and Features
- 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
- It is suitable for high temperature abrasion with corrosive environment, such as high temperature valve seats, hot work tools, cutters, gas flow valves, turbine blades and hot press screws
- It is generally applied in steel mill, chemistry, petrifaction and sugar industries

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 high temperature abrasion with corrosive environment, such as high temperature valve seats, hot work tools, cutters, gas flow valves, turbine blades and hot press screws
