These consumables are used for Mo bearing austenitic
stainless steels with 1.5 – 3% Mo.
They are also suitable for Ti or Nb stabilised and nitrogen-bearing or
free machining versions of the above alloys.
Type
316/316L steels are widely used for their good resistance to pitting, many acids and general corrosion.
The 316L consumables covered here are not suitable for 316/316H in elevated temperature structural
applications, see data sheets C-12 and C-13. For cryogenic applications (–196°C) see data sheet B-38.
Microstructure
Austenite with a controlled level of ferrite, normally in
the range 2-10FN depending on the application.
Welding guidelines
No preheat, maximum interpass temperature 250°C; no
PWHT required.
APPLICATIONS
Used to weld 18/8 stainless steels including 301, 302, 303, nitrogen bearing 304LN and titanium stabilised 321. Service temperatures are typically –100°C to about 400°C. Applications include food, brewery, pharmaceutical equipment, architectural and general fabrication, and nuclear engineering.
