ASTM A387 GR 5 CLASS 2
Good quality chromium moly alloy steel is used to make high temperature beaten steel containers. Molybdenum gives the material greater tensile strength at temperature and chromium provides better corrosion resistance.
ASTM A387 GR 9 CLASS 2
Beaten steel plate for pressure vessels and boilers used in high temperatures. Steel benefits from the addition of chromium and molybdenum, which gives the steel greater resistance to corrosion and heat. A387 Grade 9 is used by manufacturers serving the oil, gas and petrochemical industry.
ASTM A387 GR 11 CLASS 2
ASTM A387 Grade 11 Class 2 pressure vessel steel is used in various industries at elevated temperatures. It is effective, particularly in the oil, gas and petrochemical industry, where liquids and gases are stored at higher temperatures.
The higher chromium components also provide excellent resistance to corrosion and oxidation, which is essential in sour gas applications.
ASTM A387 GR 12 CLASS 2
Designed for use at elevated temperatures, ASTM A387 Grade 12 is a chromium moly alloy steel for pressure vessels and industrial boilers.
The material benefits from the addition of chromium which provides excellent resistance to corrosion and oxidation, applied in the oil and sour gas industry.
ASTM A387 GR 22 CLASS 2
We supply ASTM A387 Grade 22 Class 2 Sheet to manufacturers in the oil, gas and petrochemical industry. These industries require pressure vessel steels that perform well at elevated temperatures and our steel serves this purpose well. And with resistance to corrosion and oxidation, A387 Grade 22 Class 2 sheets are a good choice.

Characteristics of A387 Steel Sheet:
The molybdenum component in A387 steel sheet increases the tensile strength at high temperatures and also provides high resistance against oxidation and corrosion by increasing the lattice deformation of the steel structure. This prevents corrosive agents from dissolving the steel iron. A387 steel sheet is a good choice for pressure vessels against heat and acid gas environments.
A387 Steel Sheet Application:
A387 steel sheets are popularly used by the oil and gas, power plant and pharmaceutical industries.
