The surface of the stainless steel plate is smooth and has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not easily rust, but it is not absolutely not rusty.
Stainless steel plates are divided into hot-rolled and cold-rolled according to the manufacturing method, including thin cold plates with a thickness of 0.02-4 mm and medium-thick plates with a thickness of 4.5-100 mm.
In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness 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 22.214.171.124 special symbols
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, and the main role is chromium. Chromium has high chemical stability, can form a passivation film on the surface of steel, isolate the metal from the outside, 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.
