Product name：KH-SLB
 
Classification：A5.13 / ECoCr-B
 
 

  1. 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.
  2. It can be machined by carbide cutter.
  3. 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.
