KH-61-B Stick Electrode

详情

KH-61-B
Type of coating: Low hydrogen type
Weld metal contains the carbide precipitates of Cr, Mo, W and V

Classification


Application and Features 

• Weld metal contains the carbide precipitates of Cr, Mo, W and V
• It is unable to be machined and cut
• It has excellent resistance to severe metal-to-earth wear due to high hardness
• It is suitable for repairing forging molds and agitator blades

Agitator blade

Welding Position


Welding Instruction

• Dry the electrodes at 300-350°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 repairing forging molds and agitator blades
