KF-810/KCH-17-SX
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

Classification


Application and Features 

• 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
• 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
• There is no hot crack for multi-layer build-up up to 20 mm
• The weld metal can be machined and cut after welding
• It is suitable for repairing crane wheels, idlers and mine car wheels

Welding Position

Welding Instruction

• The hardness of weld metal will decrease when the temperature of stress relief exceeds 480°C
• 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

Application
- It is suitable for repairing crane wheels, idlers and mine car wheels
