AWS Class E316/316H (-15, -16, -17)
ASME SFA 5.4
WT 316/316H-16 is a filler metal that is mainly used for welding alloys where 316 is needed with improved tensile strength. This alloy contains a low carbon content of between 0.04-0.08%, which allows for a higher tensile strength at elevated temperatures. WT 316/316H-16 contains molybdenum which allows for a better creep resistance. This is often used in petrochemical industries as well as power facilities.
Tensile Strength: 75,000 psi min.
Elongation: 30% min.
Available in multiple sizes and diameters. Available in -15, -16, -17 coating.
