ASME SFA 5.28
AWS ER80S-D2; ER90S-D2
WT 80S-D2 is a mild steel solid wire that contains molybdenum for increased strength and higher levels of silicon and manganese which provides a good rust and scale tolerance as well as providing good wetting. It is best suited for pipelines and pressure vessels with temperatures of around 930°F. WT 80S-D2 has increased impact strength at low temperatures. It is suitable for both single and multiple pass welding of low alloy steels and higher strength steels in both the as welded and PWHT conditions.
Tensile Strength: 80,000 psi min.
