Product name：KCH-60CR-O
 
Classification：-
 
 

  1.  Weld metal contains primary carbide and eutectic structure.The abrasion resistance is improved due to special carbides with ultra-high hardness.
  2. It provides good weldability and almost no slag.
  3. Use 309 stainless steel electrode or KCH-13MC-O for buffer layer.
  4. It is suitable for wear plates manufacturing and repairing quarry machines, cement rolls and gyratory crusher liners.

 

Welding Instruction
  1. Weld metal is unable to be machined but it can be grounded if necessary.
  2. Preheat temperature should be 150~250°C for carbon steel, low alloy steel or cast steel base metal.
