ASTM A387 is a widely recognized standard specification for Chromium-Molybdenum (Cr-Mo) alloy steel pressure vessel plates. It is intended primarily for use in elevated temperature service where durability and high-temperature strength are crucial.
These plates are specifically designed to provide improved mechanical properties and resistance to oxidation, making them well-suited for use in high-temperature environments. ASTM A387 is commonly utilized in applications such as power plants, chemical plants, and refineries.
At Gnee , we offer a variety of A387/SA387 grades which are highly suitable for use in refineries, chemical plants, and power plants. These plates are available in Class 1 or Class 2, with additional options depending on your specific requirements.
