SPV450 Steel Plate for Pressure Vessels

SPV450 Pressure Vessel Steel Plate, under the Japanese industrial standard JIS G3115, is specifically designed for use in the manufacture of pressure vessels and boilers under intermediate temperature services. Known for its excellent weldability and superior mechanical properties, SPV450 pressure vessel plate is widely applied in industries such as petroleum, chemical, and power generation.

 

What is SPV450 Pressure Vessel Steel Plate?

SPV450 is a high-strength steel plate compliant with JIS G3115 standards, specifically designed for pressure vessels operating in intermediate temperature services. With minimum yield strength of 450MPa and tensile strength ranging 570-700MPa, this normalized steel plate offers exceptional structural integrity for critical applications like:

Boiler manufacturing

Heat exchanger systems

Petrochemical reactors

LNG storage tanks

SPV450 vs Other JIS G3115 Grades

While JIS G3115 includes six grades (SPV235 to SPV490), SPV450 stands out for:

Higher strength-to-weight ratio than SPV315/SPV355

Better intermediate temperature performance vs SPV410

More cost-effective than SPV490 for non-extreme applications

 

Mechanical Properties of SPV450 Steel Plate

SPV450 steel is designed to provide both high yield strength and tensile strength:

	50-100	430	570-700	26%
	100-200	410	570-700	20%

Supplementary Technology and Testing

SPV450 steel plates undergo a series of stringent tests to ensure their quality and performance:

Ultrasonic Testing: To detect any internal defects that could affect the material's structural integrity.

HIC (Hydrogen Induced Cracking) Test: To assess the plate's resistance to cracking in environments where hydrogen may cause embrittlement.

NACE MR0175 Compliance: This standard ensures that SPV450 is suitable for environments with the presence of hydrogen sulfide (H2S).

Low-Temperature Impact Testing: To verify the steel's performance under low temperatures, ensuring it won't fail in cold conditions.

Simulated Post-Weld Heat Treatment (PWHT): Ensures the plate's strength and durability after welding.

Steel Grades Available

SPV450 steel plates come in a range of grades to suit different strength requirements:

SPV235

SPV315

SPV355

SPV410

SPV450

SPV490

Each grade has specific yield strength and tensile strength values, with SPV450 being among the strongest, offering yield strength ≥450 MPa and tensile strength between 570-700 MPa, making it ideal for high-pressure applications.

FAQs: SPV450 Pressure Vessel Steel

Q: What's the maximum operating temperature for SPV450?
A: Designed for intermediate temperatures (-20°C to 300°C). For extreme conditions, consider SPV490 with modified alloy content.

Q: Does SPV450 require post-weld heat treatment?
A: Yes - SPWHT is mandatory unless otherwise specified in project requirements.

Q: Can I get Z35 certified SPV450 plates?
A: Yes, we provide Z-direction tested plates up to Z35 grade for critical thickness applications.
