Stainless steel sheet: two kinds of hot rolled and cold rolled according to the manufacturing method, including thin sheets with thickness of 0.5-4 mm and thick plates with thickness of 4.5-35 mm.
According to the structure characteristics of steel grades are divided into 5 categories: austenitic type, austenite-ferritic type, ferritic type, martensitic type, precipitation hardening type.
Requirements can withstand oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid and other acids corrosion, widely used in chemical, food, medicine, paper making, petroleum, atomic energy and other industries, as well as construction, kitchen utensils, tableware, vehicles, household appliances and various parts. In order to ensure that the mechanical properties of all kinds of stainless steel plates such as yield strength, tensile strength, elongation and hardness meet the requirements, the steel plate must be annealing, solution treatment, aging treatment and other heat treatment before delivery.
The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rust free.
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure, which plays the main role of chromium. Chromium has high chemical stability, can form a passivation film on the surface of the steel, isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.
