Steel For Cryogenic Service
Steel For Cryogenic Service
(OP)
I am looking for a low cost, high strength steel (bar or forging) for high pressure cryogenic service. We are currently using Nitronic 50 but it is very expensive and I feel that it is overkill for our needs. My research in various literatures led me to SA-522 Type 1 (UNS K81340). This seems to be exactly what I was looking for but I am having trouble finding it. Does anyone know where I can get this grade of steel or another name that it might go by?
Thanks.
Thanks.

Rich, I called ISG and they could not supply it and referred me to other distributors. Unfortunately all those leads turned up nothing.
Codeeng, unfortunately the 300 series austenitic stainless steels do not have the strength that I need although I am proposing to the end user to redesign the whole system based on 316 SS but I want to make sure that this is the only alternative.
Thanks again.

Looks tricky to fabricate though..

Thanks again but the one question that keeps bugging me is why no one sells or produces SA-522 Type 1 (unless I am willing to buy a heat). It seemed like the perfect solution to my problem.
