BOR-B

BOR-B is a rutile coated electrode producing an air hardening type weld metal for hardfacing of carbon and low alloy steels. The weld metal is highly resistant to abrasive wear and has a fair degree of toughness. Ideally suited for applications in which abrasion resistance is required with a fair degree of toughness. Typical applications include brake shoes, shear blades, wheels, cams, gears, pulleys, drive sprockets, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 150°C for one hour.

2. Maintain short arc and avoid weaving.

3. Use suitable buffer layers and preheating, depending on the material composition and thickness.
