宝钢309不锈钢板（Baosteel 309 stainless steel plate） Tianjin Yongqiang steel trading company: Tel:13820278327 022Liang Yongqiang Two kinds of hot and cold rolled stainless steel plate according to the method of points, including plate thickness of 0.5-4 mm and 4.5-35 mm according to the characteristics of the steel group is divided into 5 categories: Austenitic, Austenitic - Ferritic, Ferritic, martensitic, precipitation hardening. Can withstand oxalic acid, sulfuric acid, nitric acid, nitric acid and iron - copper, hydrofluoric acid, phosphoric acid, formic acid, acetic acid and various acid corrosion, widely used in chemical, food, medicine, papermaking, petroleum, atomic energy industry, as well as construction, kitchen utensils, cutlery, household appliances, various parts of the vehicle. In order to ensure the mechanical properties of various kinds of stainless steel sheet, such as yield strength, tensile strength, elongation and hardness, the steel plate must be annealed, treated by solution, aging treatment before delivery. The corrosion resistance of stainless steel depends mainly on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of the alloy. The main element is chromium. Chromium has high chemical stability, can form a passive film on the steel surface, so that the metal is isolated from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. When the passive film is destroyed, the corrosion resistance will decrease. 1 Classification by thickness (1) sheet (2) medium plate (3) thick plate (4) heavy plate 2 classification by production methods (1) hot-rolled steel sheet (2) cold rolled steel sheet 3.
