G4Si1
Low Carbon and High Strength Steel TIG SJ-50Y
Specification：AWS A5.18 ER70S-G
ISO 636-A W 46 5 4Si1
GB/T8110-2008 ER50-G
Introduction：
Suitable for 490Mpa high tensile steels and mild steel. Increased Manganese content bring higer strength than G3Si1.
Low S and P content, offering high plasticity, toughness, crack resistance, and low-temperature impact toughness.
Excellent welding performance with smooth feeding, stable arc, neat welds, low spatter.
Deposited metal has excellent mechanical properties.
Application：
Bridges
Construction structures
Automobiles
Machinery
Pipeline
Pass the certification：
CE JIS
