For welding 18% chromium – 12% nickel – 2½% molybdenum austenitic stainless steels such as 316 and 317 but with a low ferrite (i.e. FN2) it can also be used for welding 304/304L to 316/316L stainless steels in cryogenic service at temperatures down to -452 °F.

Bevel thick sections to a 60° Vee. Clean the weld zone of all contaminants. Preheating 300 series stainless steel is NOT required. Overheating stainless steel can degrade the composition and corrosion resistant properties.
