ER100S-G Welding Wire For construction machinery, hoisting machinery, bridges, pipelines, ships, pressure vessels, etc.
Specification:
1. ER100S-G has a nominal composition (wt-%) of 1.5 Mn, 0.45 Mo, 0.25 Cr, with Ni just under 1 percent (meeting NACE MR0 175
requirements). This material is designed for welding high yield strength steels and steels with tensile strengths
higher than 101ksi. It has good impact strength at low temperatures.
2. It is a is a kind of Ni,Mo,Cr type 690MPa high toughness low-alloy steel gas-shielded welding wire. It has excellent
all-position welding performance, stable arc and low spatters.
Purpose:
Suitable for welding 690MPa high strength steel structures, such as construction machinery, hoisting machinery, bridges, pipelines, ships, pressure vessels, etc.
