JIS G3115 SPV315 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 used in the fabrication of welded pressure vessels and industrial boilers where excellent performance under pressure and low-temperature conditions is required.

Chemical Composition:

The chemical composition of SPV315 is strictly controlled to ensure the necessary mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.18%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.30%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.05%

· Boron (B): ≤ 0.0015%

· Aluminum (Al): ≥ 0.020%

Mechanical Properties:

The mechanical properties of SPV315 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: ≥ 315 MPa

· Tensile Strength: 490-610 MPa

· Elongation: ≥ 20%

· Impact Energy (at -10°C): ≥ 41J

Heat Treatment:

SPV315 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 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 is capable of producing SPV315 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-4020mm

· Length: 3000mm-18000mm

Low-Temperature Impact Test:

SPV315 steel plates are subjected to a low-temperature impact test to ensure their toughness at sub-zero temperatures. The test is conducted at -10°C, and the material must meet the specified impact energy requirements to pass.

Main Applications:

Due to its excellent mechanical properties and resistance to pressure and low temperatures, SPV315 is widely used in the following applications:

· Pressure Vessels

· Industrial Boilers

· Heat Exchangers

· Storage Tanks

· Liquefied Petroleum Gas Cylinders
