Boilers and pressure vessels require materials that can withstand high pressure and temperature conditions. The type of steel commonly used for boilers and pressure vessels is known as pressure vessel steel or boiler quality steel. These steels are specifically designed to handle the stress and pressure encountered in such applications. Some common grades of steel used for boilers and pressure vessels include:
ASTM A516 Grade 70:
Widely used for pressure vessel applications due to its excellent notch toughness and weldability.
Another grade suitable for pressure vessel applications with good weldability and formability.
ASTM A387:
Alloy steel plates used for high-temperature applications in pressure vessels, offering improved corrosion and heat resistance.
EN 10028-2 P265GH:
European standard steel grade for pressure vessel applications, known for its good weldability and elevated temperature properties.
DIN 17155 HI:
German standard steel grade for pressure vessel applications, particularly suited for elevated temperature service.
SAE 4130:
Low-alloy steel often used in pressure vessel components requiring strength and toughness.
These types of steel are selected for their mechanical properties, resistance to high temperatures and pressures, weldability, and suitability for fabrication processes required in the manufacturing of boilers and pressure vessels. Compliance with relevant standards and regulations is crucial to ensure the safety and performance of these critical components.
