In Reply to: Use of Martensitic Stainless Steel in Vacuum systems posted by Jess Clarke on 04/15/02 at 7:03 AM:
I am not at all sure I can help you with this problem but I am intrigued by it. I have never heard of this kind of outgassing from Martensitic SS, although my experience with it has been limited.
What vacuum levels are you looking for? Have you considered augmenting your pumping system with something that would absorb the excess Hydrogen, such as a Titanium Sublimation Pump? What type of pumping system are you using?
Also, are you sure that the source of the Hydrogen is the SS?
As I said, I am not sure how I can help you but if you wish to e-mail me, perhaps we can work throught it. Sometimes it helps just to have someone to bounce ideas off.
