JIS G4304 SUS410 hot-rolled stainless steel plate and coil is a highly versatile material widely used in various industries due to its unique properties and capabilities. This article aims to provide a detailed introduction of the product, encompassing its chemical composition, mechanical properties, heat treatment status, dimensional range, impact testing, major applications, and supply cases from TJC Steel Group.

Chemical Composition

The SUS410 stainless steel grade adheres to strict chemical composition standards as outlined in the JIS G4304 specification. The alloy primarily consists of chromium (Cr) ranging from 11.50% to 13.50%, with carbon (C) content not exceeding 0.15%, silicon (Si) no more than 1.00%, manganese (Mn) no more than 1.00%, nickel (Ni) not exceeding 0.60%, phosphorus (P) limited to 0.040% or less, and sulfur (S) not exceeding 0.030%. This composition ensures excellent corrosion resistance and mechanical properties.

Mechanical Properties

SUS410 stainless steel plate and coil exhibit superior mechanical properties, including high tensile strength and yield strength. The yield strength is typically ≥345 MPa, while the tensile strength ranges from ≥540 MPa, depending on the heat treatment and product form. The material also possesses good ductility and elongation, with a minimum elongation of ≥25%. The hardness of SUS410, measured in Brinell Hardness (HBW), typically ranges from 159 to 201.

Heat Treatment Status

SUS410 stainless steel plate and coil are generally supplied in the hot-rolled condition, which offers good workability and formability. However, further heat treatments, such as annealing, quenching, and tempering, can be performed to enhance specific mechanical properties based on the application requirements. Annealing is typically performed at temperatures ranging from 800°C to 900°C, while quenching and tempering processes involve heating to 950°C to 1000°C and 700°C to 750°C, respectively.

Dimensional Range

JIS G4304 SUS410 hot-rolled stainless steel plate and coil are available in various thicknesses, widths, and lengths to meet diverse application needs. Common thicknesses range from 3 mm to 100 mm for hot-rolled plates and 0.2 mm to 6 mm for cold-rolled coils. Standard widths include 1000 mm, 1219 mm, 1500 mm, 1800 mm, and 2000 mm, while lengths can be customized based on customer requirements.

Impact Testing

JIS G4304 SUS410 stainless steel plate and coil undergo rigorous impact testing to ensure their reliability and safety in critical applications. The Charpy impact test, specified in the JIS Z 2248 standard, is performed to assess the material's ability to withstand sudden impacts and evaluate its toughness. SUS410 typically exhibits good impact resistance, with Charpy impact values ≥98 J/cm².

Major Applications

JIS G4304 SUS410 hot-rolled stainless steel plate and coil find extensive applications in various industries due to their corrosion resistance, mechanical properties, and workability. In the chemical industry, they are used to manufacture reactors, containers, and other equipment that require resistance to harsh chemicals.
