I came across it a while back never heard of it so a quick bit of research shows that it’s like 316 but with the addition of a small amount of titanium looks like it’s specified for areas where high temperatures are expected.Whats 321?
Thanks I will take a lookRandom Google links that might be worth a phone call:

Only stockists I could think of would be performance metals or maybe Aalco but you’d have to purchase a length from them.
Yes was a new one to me as well only saw it on a job I was polishing a piece with a big flange had the grade engraved into it.Well its a new on to me, we use 316 and 316L at work but everyday is a school day
