Weld T 309L is a nickel-chromium alloy welding wire with corrosion resistance, suitable for welding alloy steels containing 24% Cr – 13% Ni.
This alloy can also be used for welding C-Mn steel transitions and heterogeneous steel welds. When using this wire for transitions and heterogeneous welds, the weld dilution ratio needs to be controlled.
Weld T 309L has good corrosion resistance. However, when used for welding heterogeneous materials, corrosion resistance is not the primary factor.
