THE EFFECT OF THE VACUUM FURNACE DEGASSING FOR REDUCING THE STAINLESS STEEL OUT-GASSING RATE

The stainless steel out gassing rates can be reduced greatly by high temperature degassing technology in a vacuum furnace. By means of practical examples, the results of the vacuum fumace degassing, the bake out in site and the both technologies combined together were given. The advantages of the vacuum furnace high temperature degassing were analyzed. It was proved that the high temperature degassing technology has great remarkable effect to reduce the stainless steel out gassing rates and obtain an ultra high vacuum.
