MG-289 Cast Iron Welding Alloy (5 LB)
- Additional Information
High strength alloy for dirty cast iron.
Specially designed for contaminated, oil soaked cast iron.
Alloyed core wire with unique flux coating produces strong,crack-resistant welds.
For uses such as: joining cast iron to steel, transmission gear housings, gray, ductile, nodular cast iron, and sewer pipes.
Sold in 5 lb boxes
MAXIMUM STRENGTH ALLOY FOR DIRTY CAST IRON
Unique flux coating on alloyed core wire produces dense, strong, crack-resistant welds on virtually all types of cast iron. Especially good for contaminated, old, oil-soaked, dirty base metal. Also recommended for joining cast iron to steel. Use on gray, ductile, Meehanite and nodular cast iron. Deposits are machinable.
Use on machine bases, transmission or gear housings, sprockets, repair of or build-up on gears and any repair of cast iron to steel.
Typical Tensile Strength: up to 60,000 (42 kg/mm2)
Typical Hardness (HB): Brinell 210
Current: AC or DC reverse polarity (electrode +)
Diameter : 1/8"
On heavy sections, remove worn, cracked metal, and bevel joint using the US Forge Cutting rod or a grinding wheel. When repairing cracks, drill “stop” hole at either end to prevent crack travel while welding. Use short stringer beads. Use a short to medium arc length and the lowest amperage possible to minimize base metal overheating. When breaking arc, always back step into weld crater. Weld joints should be allowed to slow cool for maximum strength and machinability.
