Softening is done by heating in the 1050/ 1120C range, ideally followed by rapid cooling.Technical Data Sheet Bright Annealingmatter. 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. For common stainless steel alloys, the minimum atmosphere quality required is about -40°FTesting the inuence of solution annealing processes bright annealed versus open annealed and pickled steels in a series of extensive tests. Alternatively, open annealing heat treatment is performed in an open furnace where atmospheric oxygen causes scaling of the heat treated material. Standard specications for stainless steel tubes require that they are delivered with a scale free surface.
