Product name：KF-810/KCH-17-SX
 
Classification：-
 
 

  1. KCH-17-SX and KF-810 are a submerged arc flux-cored wire and a flux which produces a low carbon, low alloy weld deposit with a typical hardness of 35 HRC.
  2. It provides not only good metal-to-metal abrasion resistance but also good resistance to compression and cold work deformation. The impact resistance is excellent and the crack susceptibility is low.
  3. There is no hot crack for multi-layer build-up up to 20 mm.
  4. The weld metal can be machined and cut after welding.
  5. It is suitable for repairing crane wheels, idlers and mine car wheels.

 

Welding Instruction

(1) The hardness of weld metal will decrease when the temperature of stress relief exceeds 480°C.

( 2 ) The preheat and interpass temperature should be controlled between 200-400°C for massive work pieces and high curvature surface to prevent weld cracking caused by high stress.
