Description: ER309Mo Stainless Steel Welding Wire has the same composition of weld metal deposited by ER309, except for the addition of molybdenum and a small reduction in the carbon limit. It is used for welding Type 316 clad steels or for the overlay of carbon steels.

ER309LMO is used for the welding of dissimilar materials between stainless and low alloy steels, as well as for overlay cladding. This alloy is well suited for austenitic ferritic joints with a maximum application temperature of 300ºC. It is also suited for stainless with wet corrosion up to 350ºC. Alloy 309LMO is also used for depositing buffer layers when welding clad products. ER309LMO can be used for joining unalloyed/low-alloy steels/cast steel grades or stainless/heat-resistance chromium steels/cast steel grades to austenitic steels/ cast steel grades.
