304 stainless steel plates are available in various thicknesses at the factory. 304 stainless steel plates can be divided into two types: hot-rolled and cold-rolled. According to the structural characteristics of the steel type, it can be divided into five types: austenite, austenite-ferrite, Ferrite type, precipitation hardening type, martensite type. At the same time, 304 stainless steel must be able to withstand the corrosion of various acids such as oxalic acid, sulfuric acid-iron sulfate, nitric acid, phosphoric acid, formic acid and acetic acid. 304 stainless steel plates are widely used in various chemical, food, pharmaceutical, petroleum and atomic energy industries, as well as various parts including construction, kitchenware, tableware, household appliances, etc.

The surface of 304 stainless steel plate is relatively smooth, has relatively high plasticity, toughness and mechanical strength. It can resist acidic and alkaline gases, and can also resist corrosion from solutions and other media. 304 stainless steel plate is an alloy steel that is not prone to rust, but it is not absolutely immune to rust.

In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of the 304 stainless steel plate meet the requirements of each part, the steel plate must first undergo heat treatment such as annealing, solution treatment and aging treatment before delivery. .

The corrosion resistance of 304 stainless steel mainly depends on its various alloy components and its internal organizational structure. The main role is chromium. Chromium has high chemical stability and can form a passivation film on the surface of steel 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 performance will drop sharply.


304 stainless steel plate characteristics

(1) The surface of 304 stainless steel plate is beautiful and its use possibilities are very diverse.

(2) The corrosion resistance is very good, and it is longer and more durable than ordinary steel plates.

(3) The strength of 304 stainless steel plates is very high, so the possibility of using steel plates is very high.

(4) 304 stainless steel plate has high temperature resistance, oxidation and strength, so it can withstand fire.

(5) 304 stainless steel is usually processed at room temperature, which means it is easy to plasticize and is very convenient to process.

(6) No surface treatment is required, it is very simple and maintenance is also very simple.

(7) 304 stainless steel plate is easy to clean and has a very high finish.

(8) Good welding performance
