Boiler & Pressure Vessel Steel
Boiler & Pressure Vessel Steel is a type of steel used in the fabrication of boilers, pressure tanks, and industrial equipment that must withstand high pressure and high temperatures. This steel is characterized by its high strength, pressure resistance, and durability under thermal stress, making it suitable for critical applications in power plants, chemical processing, and oil & gas industries.
Key Properties of Boiler & Pressure Vessel Steel
High pressure resistance Maintains structural integrity without deformation or fracture under high internal pressure.
Excellent heat resistance Retains mechanical properties even at elevated temperatures.
Good weldability Can be welded without causing brittleness or internal structural defects.
Corrosion resistance Performs well in environments with high humidity or exposure to chemicals.
Common Grades of Boiler & Pressure Vessel Steel
ASTM A516 Suitable for pressure vessels operating at medium to high temperatures, such as oil storage tanks and boilers.
ASTM A537 High-strength steel ideal for pressure vessels that require post-weld heat treatment.
JIS G3115 (SPV series) Japanese standard steel, widely used in general industrial applications such as pressure vessels and boilers.
If you're looking for pressure vessel steel A516 or ASME A516 Grade 70 steel plates, ROCCO Steel has ready-to-ship stock available.
