Hi All, Being a machinist and working on nuclear power plants for many
years for the Navy. I do know the reasons for using 316 L over 303 or
304.It has to do with chloride stress corrosion and hardness.For use in
extracters , I would think that salt would not be a problem.I think it
would be hard to to check out what stainless sheet they are using without
going to the point of calling the factory for the info.
I don't think you will find much 316 L in sheets , but I could be wrong
there because industry changes all the time.
Best Regards
Roy
