JIS G3103 SB480 steel plate is a kind of material that is widely used in the manufacturing of boilers and pressure vessels due to its excellent mechanical properties and chemical composition. This grade of steel is designed to meet the rigorous standards required for equipment operating under high pressure and temperature conditions.

Chemical Composition:

The chemical composition of JIS G3103 SB480 is strictly controlled to ensure the material's strength and toughness. The typical chemical composition includes:

· Carbon (C): 0.15-0.21%

· Silicon (Si): 0.15-0.35%

· Manganese (Mn): 0.90-1.50%

· Phosphorus (P): ≤ 0.030%

· Sulfur (S): ≤ 0.030%

· Nickel (Ni): ≤ 0.30%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.08%

· Copper (Cu): ≤ 0.30%

Mechanical Properties:

The mechanical properties of SB480 steel plate are as follows:

· Tensile Strength: 490-610 MPa

· Yield Strength: ≥ 295 MPa

· Elongation: ≥ 22%

· Impact Energy (at -15°C): ≥ 41 Joules

Heat Treatment:

The steel is typically supplied in a normalized condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its upper critical point and then cooling it in air. This process refines the grain structure and improves the mechanical properties of the steel.

Available Dimensions:

TJC Steel Group can produce JIS G3103 SB480 steel plates in a wide range of sizes, with thicknesses ranging from 6mm to 300mm, widths up to 4000mm, and lengths up to 12000mm. Custom sizes are also available upon request.

Low-Temperature Impact Test:

SB480 steel plates are subjected to a low-temperature impact test at -15°C to ensure that the material maintains its toughness and impact resistance at low temperatures, which is crucial for applications in cold environments.
