304 stainless steel plate 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 steel: austenite, austenite ferrite, ferrite, martensite and precipitation hardening. It is required to withstand the corrosion of various acids such as oxalic acid, sulfuric acid iron sulfate, nitric acid, nitric acid hydrofluoric acid, sulfuric acid copper sulfate, phosphoric acid, formic acid, acetic acid, etc. It is widely used in industries such as chemical, food, medicine, papermaking, petroleum, atomic energy, as well as various components of buildings, kitchenware, tableware, vehicles, and household appliances.
Stainless steel plates have a smooth surface, high plasticity, toughness, and mechanical strength, and are resistant to corrosion by acid, alkaline gases, solutions, 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 two types according to the production method: hot rolled and cold rolled, including thin cold rolled plates with a thickness of 0.02-4 millimeters and medium thick plates with a thickness of 4.5-100 millimeters.
In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation, and hardness of various types of stainless steel plates meet the requirements, the steel plates must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal microstructure, with chromium playing a major role. Chromium has high chemical stability, can form a passive film on the steel surface, 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 damaged, the corrosion resistance decreases.
