ASTM A387 is the industry standard specification for Chromium-Molybdenum alloy steel pressure vessel plates. The primary intended use of these plates is in environments that are exposed to elevated temperatures. The plates are specifically designed for applications that require improved mechanical properties and resistance to oxidation, making them ideal for use in high-temperature settings.
Here at Gnee, we offer a variety of A387/SA387 Grades that are perfect for use in refineries, chemical plants, and power plants. We provide these plates in class 1 or 2 and in even more customized specifications tailored to meet our customer's specific needs.

The text describes a type of steel alloy plate composed of chrome molybdenum. This material is designed for use in pressure vessels made of weldable carbon steel that operate at high temperatures. The addition of molybdenum to the alloy gives it greater tensile strength at high temperatures, whereas the presence of chromium provides added resistance to corrosion.
When used in pressure vessels, this type of steel plate can withstand harsh conditions and maintain its structural integrity. This makes it popular in industries that require materials capable of withstanding high levels of pressure and heat. Additionally, the improved corrosion resistance provided by the chromium makes the alloy ideal for use in environments where exposure to corrosive elements is a concern.
Overall, the use of a chrome molybdenum alloy steel plate provides a high-quality option for industrial applications that require material capable of handling elevated temperature and pressure. The alloy's composition provides it with the necessary tensile strength, durability and resistance to corrosion, making it a reliable and versatile material for pressure vessel construction.
