There is a brazing vacuum furnace that we are currently using. We are experiencing various problems with it. We think that it is probably due to diffusion pump. All gaskets were renewed, difussion oil was replaced with new one. Control tests were ...Read more

I was wondering if you could kindly provide some info regarding bright annealing of 304 StSt. We have vacuum furnaces here however I require to process these parts within a hydrogen atmosphere and then rapid quench. My question is should I use a full backfill of hydrogen or perform a partial pressure control? Any advice would be greatly appreciated.

I was wondering if there are any tips or advice for securing a Viton gasket on a CF flange. One of our flanges would be opened frequently to access our samples but in trying to close it, so we cant use copper gaskets since they are not reusable. The Viton gaskets I bought on the other hand don’t have a definite form so they don’t stay in place. I was wondering if anyone can please suggest a way to install them so that the flange seals and the Viton gasket doesn’t come off each time we open the chamber. Or if there is any proper O-ring style gasket for knife-edge CF flanges. Thank you.
