6 - 8 Outgassing Rate of Stainless Steel in High Temperature based on SPP Method
Those who need a better vacuum, either in existing systems or for new construction, should be interested in this discussion, since there is at present no method of analysis to predict the bake time and temperature required to achieve a specific low outgassing rate from stainless steel. It has...
This first project re-examines stainless steel outgassing rates on a pretreated (baked) stainless steel chamber that has been stored properly under N2 for ~8 months. The outgassing rate of the sample chamber is determined mainly via the rate of rise method. The results of the rate of rise ...
1) outgassing rate 材料出气率 1. According to the material treating requirement of HIRFL-CSR ultra-high vacuum system, all stainless steel parts used for the system must be put into a vacuum furnace to degas so as to reduce theoutgassing rate. ...

The impacting surface, the indenter, was a ball bearing of carbon chromium steel with a diameter of 3.15 mm. The balanced impacting device consisted of a lever, with the longer arm Results and discussion Before performing any impact experiment, the outgassing rate from the lever device under ...
Oxidized stainless steel produced a lower outgassing rate between 3 and 5×10 −13 Torr liter/sec cm 2 . Also, a 450 °C bake for 17 h of stainless steel with the inner surface exposed to vacuum exhibited an outgassing rate of 4×10 −13 Torr liter/sec cm 2 . Aluminum baked ...
The specific outgassing rate of methane from 316 L stainless steel is found to be ⩽5×10 −22 mbar l s −1 cm −2. The outgassing of the other gases has been measured using several gauges. The specific outgassing of hydrogen is found to be 4.5×10 −15 mbar l s −1 cm...
