SUS304 (AISI 304) stainless steel is a widely used austenitic stainless steel, its chemical composition mainly includes iron (Fe), chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si) and carbon (C) and other elements. Among them, the content of chromium is between 18% and 20%, and the content of nickel is between 8% and 11%, and these two elements are the main factors that make SUS304 stainless steel have excellent corrosion resistance. Other elements such as carbon, silicon, manganese, etc. are used to adjust the mechanical properties of stainless steel.

2. Mechanical Properties 

SUS304 stainless steel plate (Coil) has excellent mechanical properties, its tensile strength, yield strength, elongation and hardness indicators are high. Its tensile strength is generally more than 520MPa, the yield strength is about 210MPa, and the elongation is more than 40%. In addition, due to its austenitic structure, SUS304 stainless steel plate (Coil) has good plasticity and toughness, and is not easy to appear brittle fracture.

3. Heat Treatment State 

Usually, SUS304 stainless steel plates (Coils) are supplied in an annealed state, which has low hardness and is easy to process. According to needs, it can also be cold Coiled or hot Coiled to get different specifications and shapes of stainless steel products. The cold-Coiled stainless steel plate (Coil) has a high hardness and is suitable for occasions where high strength and wear resistance are required.

4. Low Temperature Impact Test 

In low temperature environment, the impact toughness of SUS304 stainless steel plate (Coil) will be affected. In order to ensure its safety in low temperature environment, low temperature impact test is needed. The test mainly tests the impact resistance of stainless steel under low temperature conditions, if the test results are qualified, it indicates that the stainless steel product can be used safely in a certain low temperature environment.

5. Main Application Scenarios 

Due to its excellent corrosion resistance and mechanical properties, SUS304 stainless steel plates (Coils) are widely used in various fields. For example, in the construction industry, it can be used to make roofs, walls, railings, doors and Windows, etc. In the food processing industry, it can be used to manufacture kitchenware, food processing equipment, etc. In the chemical industry, it can be used to manufacture storage tanks, pipes, valves, etc. In addition, it is also widely used in automotive, aerospace, medical equipment and other fields.

6. TJC-Related Supply Cases
