7770 Multi-Purpose Hard Facing Buildup Stick Rod Electrode, 40 to 45 (WH) HRC Hardness, 60 to 90 Amps, AC/DCRP Polarity, 3/32"
(Pack of
5)
Restore worn steel components with ease using the 7770 Hardfacing Buildup Stick Rod Electrode. Designed for maintenance and repair technicians, this versatile buildup rod delivers a durable, wear-resistant surface that resists cracking, even under high-impact and compressive loads. Ideal for restoring shafts, gears, and crusher rolls, it works harden under impact to ensure longevity and reliability. With increased deposition rates that save time and money, and compatibility across all steel types, the 7770 Electrode guarantees efficient and effective repairs.
• Versatile – easy to use on all steels
• Resists cracking
• Increased deposition rates save time and money
• Work hardens under impact
All-position alloy for buildup on all types of steel
Elongation: 35%Hardness: Rc 45, work-hardenedPolarity: AC or DC Reverse
Typical Applications
• Shaft buildup
• Equipment part repairs – gears, booms, crusher rolls and hammers
• Welding alloy steel to manganese steel
• Frogs and switch points
• Buildup and overlay for hardfacing
• Repairs on all types of steels including manganese and stainless
• Ideal for crusher rolls, jaws, frog and switch railroad repairs
Usage ProcedureUse AC or DC reverse polarity. Electrode may be used in contact or by holding an arc. When used for joining, stringer beads are best. When used as a build-up, weaving is acceptable. Manganese steel should be kept below 550°F (288°C) by skip welding or artificial cooling. Prior to build-up, all fatigued, cracked, or spalled material should be removed. Chip slag between passes.CANNOT BE TORCH CUT
