Stainless steel plate according to the method of divided into two kinds of hot rolling and cold rolling, including 0.5-4 mm thickness plates and 4.5-35 mm thick plate, according to the characteristics of the steel group is divided into 5 classes: Austenitic, austenitic iron body, iron body, martensitic, precipitation hardening type. Can withstand the corrosion of oxalic acid, sulfuric acid and ferric sulfate, nitric acid, nitric acid and hydrofluoric acid, copper sulfate sulfuric acid, phosphoric acid, formic acid, acetic acid, etc. all kinds of acid, widely used in chemical, food, medicine, paper making, petroleum, nuclear energy and other industries, as well as the construction, kitchen utensils, cutlery, vehicles, household appliances, all kinds of spare parts requirements. In order to ensure that each kind of stainless steel plate of the yield strength, tensile strength, elongation and hardness of mechanical properties to meet the requirements, the plate before delivery must be after annealing, solid solution treatment, aging treatment of heat treatment. The corrosion resistance of the stainless steel mainly depends on its alloy composition (chrome, nickel, titanium, silicon, aluminum, etc.) and internal structure, the main role is chromium element. Chromium has a high chemical stability, can form a passivation film on the steel surface, so that the metal and the outside world to isolate, protect the steel plate is not oxidized, increase the corrosion resistance of the steel. When the passivation film is destroyed, the corrosion resistance decreases.
430 stainless steel plate has all the characteristics of 430 stainless steel, has good resistance to corrosion and general steel, better thermal conductivity than austenite, thermal expansion coefficient smaller than the austenitic, thermal fatigue, add stabilizing elements in titanium, good weld mechanical properties, mainly for building decoration, the parts of a fuel burner, home appliances and home appliance components.
430 stainless steel has the following several States, the state is not the same, the stain resistance and corrosion resistance are not the same.
NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface processing states.
