It can be divided into hot rolling and cold rolling according to the manufacturing method. It can be divided into five types according to the structural characteristics of the steel: austenite, austenite ferrite, ferrite, martensite and precipitation hardening.
It is required to withstand the corrosion of 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. It is widely used in chemical, food, medicine, paper making, petroleum, atomic energy and other industries, as well as various parts and components of buildings, kitchenware, tableware, vehicles and household appliances.
The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust free.
Stainless steel plates are divided into hot rolled and cold rolled according to the manufacturing method, including 0.02-4 mm thick thin cold plate and 4.5-100 mm thick plate.
In order to ensure that the yield strength, tensile strength, elongation, hardness and other mechanical properties of various stainless steel plates meet the requirements, the steel plates must undergo annealing, solution treatment, aging treatment and other heat treatments before delivery 05.10 88.57.29.38 special symbols.
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure. The main role is chromium. With high chemical stability, chromium can form a passive film on the steel surface to 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.
