ARCALOY 309MoL-15

Arcaloy 309MoL-15 is designed for applications requiring molybdenum with a standard 309L analysis. Ideal for cladding prior to joining stainless steel to low alloy steels. Best used out-of-position on DC current.

Features

Arcaloy 309MoL-15 is designed for applications requiring molybdenum with a standard 309L analysis. It is used primarily for welding Types 316L and 316 clad steels, or for the first layer of a molybdenum - bearing stainless steel cladding on mild or low alloy steels austenitic stainless steels - to carbon and low alloy steels, provided the service temperature is less than about 600ºF (316ºC). In the dissimilar joint, Arcaloy 309MoL can tolerate more dilution by carbon and low alloy steels than Arcaloy 309L-15. Post weld heat treatment should be given due consideration.
