The ASTM A387 specification pertains to pressure vessel plates made from Cr-Mo alloy steel. Specifically, these plates are intended for use in applications where high temperatures are present. The primary goal of these plates is to showcase improved mechanical properties and resistance to oxidation, making them an excellent fit for use in high-heat environments.
At Gnee, we offer a selection of A387/SA387 Grades that are ideal for use in refineries, chemical plants, and power plants. Depending on your specific needs, we can provide plates in class 1 or class 2, and more.

A new type of steel plate has been developed for use in high-temperature, weldable carbon steel pressure vessels. The plate is made of high quality chrome molybdenum alloy steel, which offers several advantages over traditional materials. In particular, the addition of molybdenum provides the steel with greater temperature tensile strength, making it more reliable in extreme conditions.
In addition to its improved strength, the chrome molybdenum alloy steel plate also boasts enhanced corrosion resistance thanks to the chromium content. This ensures that the material will remain intact and free from damage, even when exposed to a range of harsh environmental factors, such as moisture and chemicals.
The development of this new steel plate marks a significant advancement in the field of pressure vessel manufacturing. By offering superior strength and corrosion resistance, it helps to ensure the safe and efficient operation of critical equipment across a range of industries, from oil and gas to chemical processing.
