JIS G3115 SPV235 is a kind of steel plate for pressure vessels designed for elevated temperature service, specified by the Japanese Industrial Standards (JIS). This grade is widely used in the fabrication of welded pressure vessels and boilers due to its excellent mechanical properties and chemical composition. Below is a detailed overview of the product.

Chemical Composition:

The chemical composition of SPV235 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 SPV235 are crucial for its application in pressure vessels. The following are the typical mechanical properties:

· Yield Strength: ≥ 235 MPa

· Tensile Strength: 450 - 580 MPa

· Elongation: ≥ 22%

· Impact Energy (at -10°C): ≥ 41J

Heat Treatment:

SPV235 steel plates are generally supplied in the as-rolled condition. However, they can be normalized or normalized and tempered to enhance their mechanical properties if required by specific applications.

Available Dimensions:

TJC Steel Group offers SPV235 steel plates in a wide range of sizes to meet various project requirements. The typical available dimensions are:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4020mm

· Length: 3000mm - 18000mm

Low-Temperature Impact Test:

SPV235 steel plates are subjected to a low-temperature impact test at -10°C to ensure their toughness and resistance to brittle fracture under such conditions.

Main Applications:

Due to its excellent properties, SPV235 is commonly used in the following applications:

· Pressure Vessels

· Boilers

· Heat Exchangers

· Storage Tanks

· Columns and Towers in Chemical Plants

TJC Steel Group Supply Cases:

TJC Steel Group has a proven track record of supplying high-quality SPV235 steel plates to various industries. One notable supply case involved the delivery of SPV235 plates for a petrochemical plant in Southeast Asia. The plates were used in the construction of high-pressure vessels, where their superior strength and toughness were critical for the safety and longevity of the equipment.

In another instance, TJC supplied SPV235 steel to a power generation company for the construction of a boiler. The steel's resistance to high temperatures and its ability to withstand pressure made it the ideal choice for this application.

TJC Steel Group's commitment to quality and customer satisfaction ensures that each delivery meets the stringent requirements of the JIS G3115 standard, making it a trusted supplier of SPV235 steel plates worldwide.
