Corrosion resistance of 201 vs 304 SS.
Corrosion resistance of 201 vs 304 SS.
(OP)
We currently use 16 gauge 304 stainless steel for the outer enclosure of an autoclave. The part does not see pressure but is exposed to a small amount of steam after each steriliztion cycle. Does 201 stainless steel have comparable corrosion resistance to 304 in this environment?

RE: Corrosion resistance of 201 vs 304 SS.
Ken's other point concerning quality is well taken. I have seen samples of strip that were sold as 201 and they were not even austenitic stainless. They were mostly martensitic.
Specify alloys by UNS numbers and insist on knowing the mill of origin. If someone does not want to tell you who melted and rolled the steel them move on to another supplier.
