ASME SFA 5.18
WT 70S-2 has added deoxidants of aluminum, titanium and zirconium allowing for it to be used in welding steels that are rusty or dirty. It is often used in single-pass welding of rimmed steels, as well as killed and semi-killed, but can still be used for multipass applications. In the GTAW process WT 70S-2 produces high quality with increased toughness.
Tensile Strength: 70, 000 psi min.
