Boiler plate dealers, Hunan boiler plate, a promise Steel

 Pressure vessel plates are mainly used to make containers for use boiler plate, boiler plate supply temperature, corrosion of different containers should be selected by the board material, are not the same. Annealing: the workpiece is heated to a predetermined temperature, slow cooling holding a certain period of time after the metal heat treatment process. Annealing aims: to improve or eliminate defects in various tissues of steel casting, forging, rolling and welding process as well as residual stresses caused by the high quality boiler plate to prevent deformation of the workpiece and cracking. Commonly used in the annealing process are: fully annealed. For refinement, low-carbon steel by casting, forging and poor mechanical properties after welding of thick tissue overheating. The workpiece is heated to complete conversion of ferrite austenite temperature above 30 ~ 50 ℃, holding time boiler plate agent, and then slowly cooled with the furnace, during the cooling of austenite transformation occurs again, then the steel The organization thinner.
