Boilers And Pressure Vessel Steel Plate

 

Boilers and Pressure Vessel Steel Plate refers to a category of carbon steel and alloy steel plates specifically designed for boilers, pressure vessels, heat exchangers, reactors, and storage tanks operating under high pressure and elevated temperature conditions. These steel plates are manufactured under strict standards to ensure excellent strength, toughness, weldability, and resistance to pressure-related failure.

 

Due to their critical application environments, boiler and pressure vessel plates must comply with internationally recognized standards such as ASME, ASTM, EN, and GB, ensuring safety, reliability, and long-term performance.

 

 

Boiler and pressure vessel steels are engineered to meet demanding service conditions, offering the following key characteristics:

• High tensile and yield strength
• Excellent resistance to internal pressure
• Good toughness at low and elevated temperatures
• Stable mechanical properties after welding
• Superior resistance to cracking and deformation
• Long service life under cyclic loads

These properties make them essential materials in energy, petrochemical, and heavy industrial sectors.
