KH-60-R
Type of coating: High titania type
Weld metal is martensite structure with stable hardness but inferior toughness. It is difficult to be machined and cut

Classification


Application and Features 

• Weld metal is martensite structure with stable hardness but inferior toughness
• It is difficult to be machined and cut
• It provides excellent arc re-start, slag removal and bead appearance
• It is suitable for severe metal-to-earth wear condition, such as repairing valve brackets, pump linings and blades

Welding Position


Welding Instruction

• Dry the electrodes at 70-100°C for 30-60 minutes before use
• Preheat temperature should be ≥ 200°C and PWHT should be 600°C
• Use high tensile strength low hydrogen electrode for the buffer layer in multi-layer build-up and base metal with high hardenability

Application
- It is suitable for severe metal-to-earth wear condition, such as repairing valve brackets, pump linings and blades
