Stainless steel processing principles Chongqing Chongqing selection of stainless steel water tank stainless steel processing due to many types included in the standard grades and more, while there are a large number of widely used non-standard grades, the performance of these different grades of stainless steel screens, while there are a large number of widely used non-standard grades, grades the performance of these different, and therefore greatly appropriately select the appropriate grades of difficulty. It involves expertise in materials science, corrosion science and engineering and other disciplines, in addition, engineering experience is an important condition for the rational use of stainless steel indispensable. For a reasonable choice of stainless steel components or equipment timber following conditions shall be necessary and subject knowledge. Conditions of service, including stainless steel components or equipment corrosion medium composition, temperature, pressure, force status, life expectancy and other stainless steel trash can, is to select the prerequisites apply stainless steel. Fully understand the conditions of use of components, is a reasonable choice of stainless steel essential prerequisite. Stainless steel material should be selected according to the working conditions of components or equipment, material selection who deal with all kinds of stainless steel performance, limiting their use of environmental factors, such as whether or not readily available have a more comprehensive understanding of knowledge before they can be targeted for selection. Under the same conditions of service, practical experience in the use of stainless steel is an important basis for a reasonable selection, with special attention. In many corrosive environments, in the absence of actual conditions of experience, laboratory simulation test data or coupon data field is a reasonable choice is often critical data stainless steel material. Stainless steel surface treatment methods commonly used pieces of stainless steel surface treatment methods currently on the stainless steel surface treatment method varieties: ① surface color bleaching treatment; ② mirror-bright surface treatment; ③ surface shading. Surface color bleaching treatment: stainless steel in the process, through the coil, bar edges, welding or roasted through artificial surface heating treatment, resulting in a black oxide. This hard gray and black oxide mainly NiCr2O4 and NiF two kinds EO4 ingredients, before the general use of highly corrosive hydrofluoric acid and nitric acid removal method. However, this method costs a large, stainless steel screens decorative flowers environmental pollution, harmful, corrosive larger, gradually be eliminated. Current oxide processing methods are mainly two kinds: ⑴ sandblasting (pill) method: mainly used spray micro glass beads method, remove the black oxide surface. ⑵ chemical method: the use of a non-polluting pickling and passivation paste and room temperature, non-toxic cleaning solution with inorganic additives were immersion. So as to achieve the purpose of whitening qualities of stainless steel. After the deal appears to be basically a dull color. This method for large-scale, complex products more suitable.
