ASME SFA 5.28
WT 80S-Ni1 is a low alloy copper coated metal containing 1% nickel, allowing for welding of low temperature applications, as low as -50°F. The added nickel content increases the weathering resistance as well as improving the electrochemical balance of weld and base metal. PWHT is not required but preheat and interpass temperature is 300°F.
Tensile Strength: 87,000 psi min.
Yield Strength: 73,950 psi min
Elongation: 25% min.
Available in multiple sizes and diameters.
