C ≤ 0.08%

Si ≤ 1.00%

Mn ≤ 2.00%

P ≤ 0.045%

S ≤ 0.030%

Ni ≥ 3.00%

Cr ≥ 18.00%

N ≥ 0.15%

 

Mechanical Properties

The mechanical properties of SUS304N stainless steel make it suitable for a range of applications. The material exhibits good tensile strength, ductility, and impact strength. Typical mechanical properties include an ultimate tensile strength of at least 520 MPa and a yield strength of at least 210 MPa. The material also exhibits good fatigue resistance and is suitable for cyclic loading applications.

 

Production Method

The production of SUS304N stainless steel sheet (coil) involves several processes. The initial steps involve the hot rolling and cold rolling of the steel to achieve the desired thickness and surface finish. The steel is then annealed to optimize its mechanical properties. Finally, the material is subjected to a series of quality checks to ensure it meets the required standards.

 

Heat Treatment State

The heat treatment state of SUS304N stainless steel sheet (coil) depends on the specific application requirements. Typical heat treatment processes include annealing and stress relief annealing, which are used to optimize the material's mechanical properties and corrosion resistance. The heat treatment process also affects the material's surface finish and dimensional stability.

 

Low-Temperature Impact Testing

To ensure the material's performance in low-temperature environments, SUS304N stainless steel sheet (coil) undergoes low-temperature impact testing. This testing involves subjecting the material to sudden impact at low temperatures and evaluating its ability to withstand the stress without fracturing or excessive deformation. The results of these tests provide valuable information on the material's toughness and resistance to brittle fracture.

 

Key Application Scenarios

The exceptional corrosion resistance and mechanical properties of SUS304N stainless steel sheet (coil) make it suitable for a range of applications, including:

Automotive components, such as exhaust systems and body panels.

Infrastructure components, including bridge supports and building facades.

Industrial equipment, including pressure vessels and reactors.
