AWS Class ER316LMn
ASME SFA 5.9
WT 316LMn is an austenitic stainless steel bare welding wire with no ferrite. WT 316LMn is typically used in welding, repairing, and overlaying of stainless steels like 316L, as well as types like 201, 304L, 316L, and 3% and 9% Nickel steels, when the ferrite levels are needed to be low. WT 316LMn is used for GMAW, GTAW, and SAW welding. It is often used in the cryogenic industry to get a low impact toughness and high strength. Weld metal results performed at -350°F and -452°F result in impact strengths of 25 ft-lbs and 15 mils lateral expansion.
Tensile Strength: 100,000 psi
Yield Strength: 63,000 psi
Impacts at -320°F: 35-38 MILS Lateral Expansion
Available in multiple sizes and diameters in spool and wire rods.
