ASTM A662 Grade B steel plate is a carbon-manganese-silicon steel plate designed for moderate and lower temperature pressure vessel applications, adhering to the ASTM A662/A662M standard.
Characteristics
High Strength and Toughness
ASTM A662 Grade B steel plate exhibits excellent mechanical properties, including high strength and toughness, making it suitable for pressure vessels operating under moderate to low temperature conditions.
It typically has a tensile strength in the range of 450-585 MPa (65-85 ksi), ensuring its ability to withstand significant pressure without deformation.
Good Weldability
The steel plate is designed to have good weldability, which is crucial for pressure vessel fabrication. It can be easily welded using common welding processes without compromising its mechanical properties.
Impact Toughness at Low Temperatures
ASTM A662 Grade B steel plate maintains good impact toughness at low temperatures, making it suitable for applications in cold regions or where the pressure vessel may be exposed to low-temperature environments.
Chemical Composition Control
The steel plate's chemical composition is carefully controlled to ensure optimal mechanical properties and weldability. It contains appropriate amounts of carbon, manganese, silicon, and other alloying elements to achieve the desired balance of strength, toughness, and corrosion resistance.
