Technical Data Sheet Bright AnnealingFor bright annealing to be effective, tube surfaces must be clean and free of foreign matter. The annealing atmosphere must be relatively free of oxygen (if a bright result is desired). This is accomplished by removing nearly all gas (creating a vacuum) or by displacement of oxygen and nitrogen with dry hydrogen or argon. ForFile Size: 367KBPage Count: 6

Especially for smaller dimensions it helps to fulfill the required high quality material properties. Quality Check and CertificationKeeping stainless steels stainless - The FabricatorStainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface1. This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface. Under these conditions, the surface is passive, or resistant to corrosion. Failure to develop and maintain this passive film renders the surface active, or possessing corrosion resistance similar to conventional sSee more on thefabricator bright annealing gas steel tube steels
