Washington Alloy, TF309LMO1603, Welding Electrode, E309LMo-16, 5/32 in.

309LMo LowCarbon was developed for welding 22-27% Cr-11-15% Mi –2-3% Mo stainless steel, austenitic stainless steel containing molybdenum to mild or carbon steel and for welding ferritic steel plates clad with AISI 316 stainless steel. This electrode yields an austenitic ferritic, crack resistant weld deposit that will provide corrosion resistance against sulfuric acid, phosphoric acid, etc. 309LMo weld deposits have a tensile strength greater than that of USA 309 or USA 309L. It is typically used for overlaying carbon steel giving weld deposits analogous to 316 stainless steel.
