KH-50 Stick Electrode

Description

KH-50
Type of coating: Lime titania type
Weld metal is martensite structure with13%Cr

Classification


Application and Features 

• Weld metal is martensite structure with13%Cr
• Due to the high hardness of the weld metal, preheat and stress relieving is required to prevent cracks
• It provides excellent corrosion resistance; acid resistance and impact wear resistance at high temperature
• It is suitable for repairing conveyers, crane wheels, drive tumblers and chemical conveying screws

Mixer Screw

Welding Position


Welding Instruction

• Dry the electrodes at 200-250°C for 30-60 minutes before use
• Preheat temperature should be above 200°C. Use slow cooling and stress relieving after welding

Application
- It is suitable for repairing conveyers, crane wheels, drive tumblers and chemical conveying screws
