Lincore® 55-G

Flux-Cored Gas-Shielded (FCAW-G)

Low Alloy steels designed for rebuilding of carbon or low alloy parts used in applications involving non-lubricated rolling or sliding Metal-to-Metal wear, and in applications with severe abrasion accompanied by low or moderate impact, works best in Metal-to-Earth applications.

DETAILS

Low Alloy steels designed for rebuilding of carbon or low alloy parts used in applications involving non-lubricated rolling or sliding Metal-to-Metal wear, and in applications with severe abrasion accompanied by low or moderate impact, works best in Metal-to-Earth applications.

Features
