TMW Low Alloy Steel Solid Mig CO2 Welding Wires ER70S-2 ER70S-3 ER70S-4 ER80S-D2

ER70S-2

AWS A5.18 ER70S-2

Description：

ER70S-2 is a premium wire for welding on all grades of mild and carbon steels, producing quality welds with minimal porosity. It is a triple deoxidized wire (Zirconium, Titanium, and Aluminum) making it an excellent choice for welding over rust and mill scale.  Used for carbon steels and alloy steels with 500MPa tensile strength structures welding, and high speed welding of sheet plates and pipelines.

ER80S-D2

AWS A5.28 ER80S-D2

Description：

ER80S-D2 is a low alloy copper-coated tig rod with 0.5% Mo content designed for welding low-alloy steels with high tensile strength and creep resistance. It shows good impact strength at low temperatures and suitable for pipelines and pressure vessels with operating temperatures of about 500°C. It will also find applications for the repair of medium strength steel castings
