JIS G3115 SPV450 is a kind of steel plate for pressure vessels designed for use in environments where high strength and good toughness are critical, especially at low temperatures. This grade is widely recognized for its excellent performance in various industrial applications, including petrochemical, chemical processing, and power generation.

Chemical Composition:

The chemical composition of JIS G3115 SPV450 is strictly controlled to ensure the material's mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.18%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Niobium (Nb): ≤ 0.05%

· Vanadium (V): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Boron (B): ≤ 0.004%

· Aluminum (Al): ≥ 0.020%

Mechanical Properties:

The mechanical properties of SPV450 are characterized by its high strength and good toughness, which are essential for pressure vessel applications. The typical mechanical properties are as follows:

· Yield Strength: ≥ 450 MPa

· Tensile Strength: 570 - 720 MPa

· Elongation: ≥ 18%

· Impact Energy (at -10°C): ≥ 47 J

Heat Treatment:

SPV450 steel plates are generally supplied in the normalized condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its critical range 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 offers JIS G3115 SPV450 steel plates in a wide range of sizes to meet the specific requirements of our customers. The typical available dimensions are:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4000mm

· Length: 3000mm - 18000mm

Low-Temperature Impact Test:

SPV450 steel plates are subjected to a low-temperature impact test to ensure their toughness at sub-zero temperatures. The standard Charpy V-notch impact test is conducted at -10°C, with a minimum impact energy of 47 J.

Main Applications:

Due to its excellent mechanical properties and resistance to low-temperature brittle fracture, SPV450 is commonly used in the fabrication of pressure vessels, boilers, and other equipment that operate under severe conditions. It is particularly suitable for applications in the oil and gas industry, chemical processing plants, and power generation facilities.
