SUS904L stainless steel plate (Coil), also known as AISI 904L stainless steel, is a highly corrosion-resistant stainless steel material. It is favored by the industry for its excellent mechanical properties, excellent corrosion resistance and wide application fields. This paper will deeply discuss the chemical composition, mechanical properties, heat treatment state, low temperature impact test and main application scenarios of SUS904L stainless steel plate. In addition, relevant supply cases of TJC Steel Group as a quality supplier will be presented.

2. Chemical Composition

The chemical composition of SUS904L stainless steel plate mainly includes iron (Fe), chromium (Cr), nickel (Ni), copper (Cu) and molybdenum (Mo) and other elements. Among them, the content of chromium is between 19.00% and 21.00%, the content of nickel is between 4.00% and 6.00%, the content of copper is between 1.00% and 3.00%, and the content of molybdenum is between 2.00% and 3.00%. The precise ratio of these elements gives SUS904L stainless steel plate excellent corrosion resistance, so that it can maintain stable performance in harsh environments such as strong acids and alkalis.

3. Mechanical Properties

In terms of mechanical properties, SUS904L stainless steel plate shows high strength and good toughness. Its tensile strength is usually greater than or equal to 620MPa, and its yield strength is in the range of 310-480 mpa. In addition, the material also has good plasticity and toughness, and can withstand large deformation without breaking. These characteristics make SUS904L stainless steel plates ideal for manufacturing equipment that can withstand high loads and corrosive environments.

4. Heat Treatment State

SUS904L stainless steel plates are usually supplied in an annealed state to maintain their good workability. In cases where it is necessary to further optimize its mechanical properties and corrosion resistance, solid solution treatment or stabilization treatment can be performed. With proper heat treatment, the microstructure and properties of the material can be contCoiled to meet the needs of a specific application.

5. Low Temperature Impact Test

In order to evaluate the toughness of SUS904L stainless steel plate in low temperature environment, low temperature impact test is required. This test evaluates the low temperature toughness of steel plates by measuring the impact absorption work at different temperatures. The good low temperature impact performance indicates that the material can maintain good toughness and brittle fracture resistance at low temperature. This makes the SUS904L stainless steel plate ideal for applications in extremely cold environments, such as oil and gas drilling platforms, ships and other key structural components.

6. Main Application Scenarios

Due to its excellent corrosion resistance and high temperature properties, SUS904L stainless steel plates are widely used in various industrial fields. It is mainly used to manufacture equipment and components that need to withstand highly corrosive and high-temperature environments, such as reactors, heat exchangers, storage tanks and pipeline systems in petrochemical, power energy, Marine engineering and other industries. In addition, in the food processing, pharmaceutical and medical device industries, due to its high requirements for hygiene and cleanliness, SUS904L stainless steel plate has also been widely used.
