SEMI F20 (316L VIM/VAR) sourcing

[iepeulas]

Does anyone know where to find semiconductor grade steel that meets the SEMI F20 UHP specification. Its basically 316L with some additional chemistry and inclusion content requirements.

I've found a few places that will make it, but I do not want to commision a mill run. Does anyone know of a distributor of smaller quantities.

Thanks,

Jeremy

I have need high prurity stainless steel in the past for corroion resistance applications. I went to Alleghney and Outokumpu and was able to cherry pick mill certs and found what I needed in small quantities. Might work since both make very good, high quality heats.

For remelted you are probably stuck with Cartech and Universal.

I'm looking for round bar, 3/8" dia. or so. Anything larger could work too, I'll just centerless grind down to my target dia.

I can't find material with this spec anywhere, in any form. Everyone wants to sell a mill run...
