JIS G4304 SUS304N2 hot-rolled stainless steel plates and coils are renowned for their exceptional chemical composition, mechanical properties, and wide range of applications. These materials, manufactured according to the stringent Japanese Industrial Standards (JIS), offer a unique blend of durability, strength, and corrosion resistance.

Chemical Composition

SUS304N2 stainless steel is a modified version of the popular SUS304 grade, with the addition of nitrogen (N) and niobium (Nb). This composition results in a steel alloy with improved strength while maintaining good ductility. The chemical composition includes carbon (C) ≤ 0.08%, silicon (Si) ≤ 1.00%, manganese (Mn) ≤ 2.50%, phosphorus (P) ≤ 0.045%, sulfur (S) ≤ 0.030%, chromium (Cr) 18.00-20.00%, nickel (Ni) 7.50-10.50%, nitrogen (N) 0.15-0.30%, and niobium (Nb) ≤ 0.15%.

Mechanical Properties

In the solution heat-treated condition, SUS304N2 stainless steel plates and coils exhibit excellent mechanical properties. They possess a hardness of HB 250 or below, a tensile strength of over 690 N/mm², a yield strength of 45 N/mm² or above, and an elongation of 35% or more. These properties ensure that SUS304N2 stainless steel is suitable for a wide range of demanding applications.

Heat Treatment

SUS304N2 stainless steel plates and coils are typically solution heat-treated to optimize their mechanical properties. This process involves heating the steel to a specific temperature and then cooling it rapidly to achieve the desired microstructure. Solution heat treatment ensures that the steel retains its corrosion resistance and mechanical properties over time.

Dimensional Range

JIS G4304 specifies the dimensional range for SUS304N2 hot-rolled stainless steel plates and coils. The thickness of the plates can vary, with specific thicknesses and widths available to meet the needs of different applications. Similarly, the coils can be produced in various diameters and widths to suit various processing requirements.

Impact Testing

To ensure the reliability and safety of SUS304N2 stainless steel plates and coils, impact testing is performed. This test simulates the effect of sudden impact loads on the material and assesses its ability to resist fracture. SUS304N2 stainless steel exhibits excellent impact toughness, ensuring its suitability for applications where impact loads are a concern.

Applications

SUS304N2 stainless steel plates and coils find extensive applications in various industries. They are commonly used in the chemical, oil and gas, pharmaceutical, and food processing industries due to their excellent corrosion resistance and hygiene properties. In addition, their strength and ductility make them suitable for use in construction, automotive, and other demanding applications.
