Is Austenitic 303 NACE compliant?
Is Austenitic 303 NACE compliant?
(OP)
I have a copy of MR0175 and section 3.5 describes Austenitic SS. But Table 1 doesn't list 303. Why? 302 and 304 is listed and OK per NACE if Rc<22 in the annealed condition.
Was it left out for a reason or just left out. I have a part to make that may see H2S service. Can I use annealed 303? Thanks for the help. -awol

We do not use 303 at all.
The āLā grades are used to provide extra corrosion resistance after welding. The letter āLā after a stainless steel type indicates low carbon (as in 304L). The carbon is kept to .03% or under to avoid carbide precipitation.
