Whether stainless steel plate or heat-resistant steel plate, austenitic steel plate has the best comprehensive performance, with sufficient strength, excellent plasticity, and low hardness, which is also one of the reasons why they are widely used. Austenitic stainless steel is similar to most other metal materials in terms of tensile strength, yield strength, and hardness, which increase with the decrease of temperature; Plasticity decreases with decreasing temperature. Its tensile strength increases relatively uniformly within the temperature range of 15-80 ° C. More importantly, as the temperature decreases, its impact toughness decreases slowly and there is no brittle transition temperature. So stainless steel can maintain sufficient plasticity and toughness at low temperatures. The heat resistance of stainless steel refers to its ability to resist oxidation or gas medium corrosion at high temperatures, which is also known as thermal stability.

Stainless steel is a versatile stainless steel that is widely used in the production of equipment and parts that require good comprehensive performance (corrosion resistance and molding).In order to maintain the corrosion resistance inherent in stainless steel, stainless steel plate must contain more than 18% chromium and more than 8% nickel content.

Austenitic Stainless Steel coil
stainless steel coil with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.

Most usage requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted. However, other applications are increasingly seeking structural integrity or impermeability. For example, the roofs and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than aesthetics, even if the surface is not very clean. 304 stainless steel is very effective in dry indoor environment.
