KH-22CANE Stick Electrode

Description

KH-22CANE
Type of coating: Special type
Weld metal contains carbide precipitates of Cr. It has the best resistance to high temperature abrasion and earth abrasion. The abrasion resistance is exceptional in corrosive conditions

Classification


Application and Features 

• Weld metal contains carbide precipitates of Cr. It has the best resistance to high temperature abrasion and earth abrasion. The abrasion resistance is exceptional in corrosive conditions
• The service temperature can be up to 650°C
• It provides stable arc, easy arc re-start and almost no slag
• It is specially designed for repairing pressing roller of sugar refinery due to its corrosion resistance to sugar cane juice
• It provides a hemisphere weld bead

Welding Position


Welding Instruction

• Dry the electrodes at 100-200°C for 30-60 minutes before use.
• Preheat temperature should be ≥ 250°C and PWHT should be 600°C.
• Weld beads should be put down in grid shape to prevent the surfacing layers from spalling

Application
