Product Description:
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.

Applications:
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.
