Similar to 309 with the exception for the addition of 2.0 – 3.0% molybdenum to increase its pitting corrosion resistance in halide-containing environments.
Primary application for this fi ller metal is surfacing of base metals to improve their resistance to corrosion. The 309LMo is used to achieve a single-layer overlay with a chemical composition similar to that of a 316L stainless steel.
Also used for the fi rst layer of a multilayer overlays with fi ller metals such as 316L or 317L stainless steel
