ASTM A387 GR 5 CLASS 2
A high quality chrome molybdenum alloy steel plate intended specifically for use in weldable carbon steel pressure vessels at elevated temperatures. Added molybdenum gives the material greater temperature tensile strength and the chromium provides improved corrosion resistance.
ASTM A387 GR 9 CLASS 2
Weldable carbon steel plates for pressure vessels and boilers used in elevated temperatures. The material benefits from added chromium and molybdenum which gives the steel greater corrosion resistance and resistance to heat. A387 Grade 9 is used by fabricators who serve the oil, gas and petrochemical industry.
ASTM A387 GR 11 CLASS 2
A pressure vessel grade steel for use in elevated temperature service, ASTM A387 Grade 11 Class 2 is used in a variety of industries and is highly effective, particularly in the oil, gas and petrochemical industry, where liquids and gases are often stored at higher temperatures.
The higher levels of chromium also provide excellent corrosion and oxidation resistance, which is a must in sour gas applications.
ASTM A387 GR 12 CLASS 2
Engineered for use in elevated temperature service, ASTM A387 Grade 12 is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers.
The material benefits from added chromium which provides excellent corrosion and oxidation resistance making it ideal for sour service applications in the oil and gas industry.
ASTM A387 GR 22 CLASS 2
We supply ASTM A387 Grade 22 Class 2 plates to fabricators serving the oil, gas and petrochemical industry. These industries require a pressure vessel grade steel which works well in elevated temperatures and our material serves this purpose well. And with good corrosion and oxidation resistance, A387 Grade 22 Class 2 plates are a good option.

Features of A387 steel plate:
The Molybdenum component in A387 steel plate increases the plate tensile strength at high temperatures, and it also provides high resistance against oxidation and corrosion by increasing the lattice strain of the steel structure. That effectively stops the corrosive agents from dissolving the iron out of the steel structure.A387 steel plate are good option for heat-resistant pressure vessels and sour gas environments.
Application of A387 steel plate:
A387 steel plate are popular used by power plant and dignity health medical foundation oil and gas industries in the production facilities because of the alloy’s key properties.
