ASME SFA 5.4
WT 309LMo-16 is an electrode that is available in -15, -16 coating. This electrode was created to best weld metals requiring a 309L analysis but needing the molybdenum component. WT 309LMo-16 has a low carbon content to reduce the likelihood of intergranular corrosion, as well as increase the ferrite content. This electrode was designed to weld stainless steel to other types of steel and for depositing buffer layers when welding acid-resisting clad steels.
Tensile Strength: 75,000 psi min.
Elongation: 30% min.
Available in multiple sizes and diameters.
