A387 Grade 22 alloy carbon steel plates are a type of high-strength, low-alloy (HSLA) steel that conform to the ASTM A387/A387M standard specification. This grade is specifically designed for elevated temperature service and is commonly used in the manufacturing of boilers and pressure vessels.
The "Grade 22" designation indicates that this steel has a specified minimum yield strength of 310 MPa (45,000 psi) and a minimum tensile strength of 515-690 MPa (75,000-100,000 psi). It contains chromium and molybdenum as key alloying elements, providing increased resistance to oxidation and high-temperature strength.
These plates are produced through normalizing and controlled rolling processes, which enhance their mechanical properties and make them suitable for applications requiring reliable performance at elevated temperatures.
A387 Grade 22 alloy carbon steel plates find application in industries such as petrochemical, oil and gas, power generation, and chemical processing. They possess excellent corrosion resistance and offer good weldability and formability.
These plates can be further processed through cutting, bending, and welding to meet specific project requirements. A387 Grade 22 provides a combination of strength, toughness, and high-temperature resistance, making it an ideal choice for pressure vessels and boilers operating under demanding conditions.
