HARD FACING ELECTRODES

Description: A medium – heavy coated electrode ,depositing an air hardening type weld metal which has excellent resistance to severe abrasion and frictional wear .The electrode operates on both DC(-) and AC displaying good operating characteristics. A buffer layer of SUDO 7016 is recommended on hand base material .The weld metal is non–machinable.

Applications:

• Gears & Gear wheels .
• Oil expeller worms.
• Scraper blades, concrete mixer blades .
• Screw conveyers .
• Cement die rings.
• Clinker mill liner plates etc.

Description: A medium coated, rutile type, hardfacing electrode depositing an air hardening type weld metal having hardness in the range of 56-59 HRC .The electrodes which operates on both AC and DC displays pleasing operating characteristics. Weld deposits are extremely hard and resistant to wear by abrasion and moderate impact

Applications:

• Hard facing of cutting and forging tools.
• Drill bits, shears and choppers.
• Oil expeller worms.
• Wire drawing drums, crane wheels, etc.

Description: An AC/DC (+) type hard facing electrode depositing weld metal which contains 17% Cr and 4% Mn. The weld deposit which is initially soft work hardens quickly under impact in service and displays superior resistance to abrasion and impact, Ideal for buffer before laying hard deposits.

Applications:

• Hard facing of crusher jaws.
• Roll crushers.
• Crusher hammers.
• Dipper teeth & buckets.
• Mining machinery.

Description: A heavy coated AC/DC type electrode depositing weld metal which has high proportion of chromium carbide. The weld deposit is extremely hard (59-63 HRC) and has excellent resistance to severe abrasion and frictional wear. The weld metal retains its hardness at elevated temperature up to 5000C and is resistance to oxidation up to 10000C.The electrode is easy to operate in down hand and vertical up positions.

Applications:

• Conveyer Screws.
• Plough Shares.
• Cultivator shovels.
• Grinder rings.
• Edge runner scrapers.
• Mining equipment.
• Blast furnace bells and hoppers.
