The ASTM A387 specification governs the production of pressure vessel plates made from Cr-Mo alloy steel. These plates are specifically designed for use in high-temperature applications, where they must demonstrate excellent resistance to oxidation and other forms of thermal degradation. They are intended primarily for use in pressure vessels, where their superior mechanical properties can help ensure safe and reliable operation even under extreme conditions.
At Gnee, we understand the importance of high-quality materials for the energy and chemical industries. That's why we offer a range of A387/SA387 Grades that are tailored to meet the needs of refineries, chemical plants, and power facilities. Our plates are available in both class 1 and class 2 versions, providing customers with the flexibility to select the product that best meets their specific requirements.
Whether you need plates for high-temperature service or other demanding applications, you can count on Gnee to deliver the reliable, high-performance materials you need. Contact us today to learn more about our full line of ASTM A387/SA387 Plates!
