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
