Lincore® 55-G

Flux-Cored Gas-Shielded (FCAW-G)

CLASSIFICATIONS:
EN ISO : T Fe2

LINCORE® 55-G Metal-Cored Wire ideal for carbon steel and low alloy steel, produces a deposit which resists metal-to-metal wear and mild abrasion. Unlimited layers with proper preheat and interpass temperatures and procedures (Metal-to-Metal)

DETAILS

LINCOREĀ® 55-G Metal-Cored Wire typical application on Crane wheels, Blower blades, Bucket lips, Dredge parts and Tillage tools deposit results in an even harder material when used with the Bulk Tungsten Carbide process for all welding positions except overhead.
