KF-810/KCH-31-SX
Weld metal is martensite structure with low carbon and low alloy content

Classification


Application and Features 

• Weld metal is martensite structure with low carbon and low alloy content
• It can be machined, forged and hardened
• It is suitable for repairing continuous casting rolls, steel mill rolls, shafts and idlers. It can also be used as the buffer layer for hardfacing

Welding Position

Welding Instruction

• The DC (+) polarity is recommended, but AC polarity can be used in some special automatic application
• The dust, oil and moisture of surface should be removed before welding. If weld surface has crack or chip, please use a low hydrogen electrode to fill it before repairing

Application
- It is suitable for repairing continuous casting rolls, steel mill rolls, shafts and idlers. It can also be used as the buffer layer for hardfacing
