Description:
WT 80S-B3L is creep resistant mild steel and are often used in chemical industries. Preheat and interpass temperatures are usually kept between 375-425°F. It has a lower carbon content which allows for greater resistance to cracking and is often best suited for welds left in as-welded condition.
Tensile Strength: 80, 000 psi min.
Yield Strength: 68,000 psi min
Elongation: 17% min.
Available in multiple sizes and diameters.
