Use & Application
Used to weld 18/8 stainless steels including 301, 302, 303, nitrogen bearing 304LN and titanium stabilized 321. Service temperatures are typically –100°C to about 400°C. Applications include **food, brewery, pharmaceutical equipment, architectural and general fabrication, and nuclear engineering**. The 308L consumables covered here are not suitable for 304/304H in elevated temperature structural applications, see data sheets C-10 and C-12. For cryogenic applications (–196°C) see data sheet B-37. No preheat, maximum interpass temperature 250°C; no PWHT required.
Alloy type
308L austenitic stainless steels for joining 304L base materials.
Microstructure
Austenite with a controlled level of ferrite, normally in the range 3-12FN depending on the application.
