In the realm of stainless steel, the JIS G4304 SUS301 hot-rolled stainless steel plates and coils occupy a significant position, renowned for their superior properties and versatile applications. This article aims to provide a detailed introduction to the chemical composition, mechanical properties, heat treatment status, dimensional range, impact testing, major applications, and relevant supply cases from TJC Steel Group.

Chemical Composition:

The SUS301 stainless steel is characterized by its low nickel (Ni), chromium (Cr), and high nitrogen (N) content. It typically comprises carbon (C) ≤ 0.15%, silicon (Si) ≤ 1.00%, manganese (Mn) ≤ 2.00%, sulfur (S) ≤ 0.030%, phosphorus (P) ≤ 0.045%, chromium (Cr) ranging from 16.00 to 18.00%, and nickel (Ni) between 6.00 and 8.00%.

Mechanical Properties:

SUS301 stainless steel exhibits remarkable mechanical properties, including a tensile strength (σb) of ≥ 520 MPa, a conditional yield strength (σ0.2) of ≥ 205 MPa, an elongation rate (δ5) of ≥ 40%, a reduction of area (ψ) of ≥ 60%, and hardness values not exceeding 187 HB, 90 HRB, or 200 HV.

Heat Treatment Status:

The SUS301 stainless steel plates and coils are typically supplied in a heat-treated condition, specifically a solution treatment at a temperature ranging from 1010 to 1150°C followed by rapid cooling. This heat treatment ensures the material achieves its desired metallurgical structure and properties.

Dimensional Range:

JIS G4304 SUS301 stainless steel plates and coils are available in a wide range of dimensions to cater to various applications. Standard sizes include, but are not limited to, 1219mm x 2438mm, 1219mm x 3048mm, and 1219mm x 6096mm, with custom sizes also available upon request.

Impact Testing:

SUS301 stainless steel undergoes rigorous impact testing to ensure its structural integrity and resistance to sudden loads. These tests are performed in accordance with industry standards and specifications.

Major Applications:

The versatile nature of JIS G4304 SUS301 stainless steel plates and coils finds extensive applications across various industries. They are commonly used in the automotive industry for lightweight components, in the food processing sector for corrosion-resistant equipment, and in the construction and decoration industries for their aesthetic appeal and durability.
