The surface of the 304 stainless steel plate is smooth, 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 is not easily rusted, but it is not absolutely rust-free.
The 304 stainless steel plate is divided into two types of hot rolling and cold rolling according to the method, including a thin cold plate having a thickness of 0.02-4 mm and a medium plate having 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 all kinds of 304 stainless steel plates meet the requirements, the steel plates must be subjected to heat treatment such as annealing, solution treatment and aging treatment before delivery. 05.10 126.96.36.199 special symbols
The corrosion resistance of 304 stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure. The main role is chromium, which has high chemical stability.
A passivation film can be formed on the surface of the steel to isolate the metal from the outside, protect the steel sheet from oxidation, and increase the corrosion resistance of the steel sheet. After the passivation film is destroyed, the corrosion resistance is lowered.
