ASTM A387 Steel Plate For Pressure Vessel And Oil Industry

In the pressure vessel and oil & gas industries, the safety and durability of equipment directly depend on the quality of core materials. ASTM A387 steel plate, as a premium chromium-molybdenum alloy steel, has become the first choice for high-temperature and high-pressure applications due to its excellent performance.

GNEE Steel, as a professional ASTM A387 steel plate supplier, provides high-quality products that fully comply with international standards, empowering global energy and chemical projects.

ASTM A387/A387M is a specification developed by the American Society for Testing and Materials (ASTM) that covers chromium-molybdenum alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service ASTM International. Its ASME counterpart is SA387, which is widely used in pressure vessel construction worldwide .

The defining characteristic of ASTM A387 is its carefully balanced alloy composition, where chromium provides oxidation and corrosion resistance, while molybdenum enhances high-temperature strength and creep resistance . These plates are available in multiple grades (2, 5, 9, 11, 12, 22, 21, and 91) and two classes (Class 1 and Class 2), each tailored for specific operating conditions .

ASTM A387 steel plates deliver a unique combination of properties that make them indispensable in the oil and gas sector :

High-Temperature Performance: Maintains strength and ductility at elevated temperatures, resisting creep and thermal fatigue-essential for equipment operating in oil refining and petrochemical processes .

Corrosion Resistance: Specifically formulated to combat hydrogen corrosion, hydrogen embrittlement, hydrogen stripping, and sulfide corrosion in medium-temperature hydrogen environments (350-480°C), common in oil refining operations .

Weldability: Designed for easy welding with appropriate preheating and post-weld heat treatment (PWHT), ensuring structural integrity in complex pressure vessel fabrication .

Mechanical Strength: Offers excellent tensile strength (450-760 MPa) and yield strength (275-415 MPa) depending on grade and thickness, providing reliable performance under high pressure

What is ASTM A387 material?

ASTM A387 is the technical delivery standard covering the supply of chrome molybdenum pressure vessel alloy steel plates. The introduction of chrome molybdenum increases the materials temperature tensile strength making it an excellent choice for elevated temperature environments.

What is ASTM A387 Grade 11 equivalent to?

ASTM A387 grade 11 equivalent steel is ASME SA387 grade 11. ASTM A387 grade 11 covers A387 grade 11 class 1 and A387 grade 11 class 2, which are equivalent to ASME SA387 grade 11 class 1 and SA387 grade 11 class 2 respectively.

What is the ASTM A387 Grade 22 equivalent to?

Among the ASTM A387 Grade 22 equivalent steel grades, SA387 Grade 22, 10CrMo9-10 is more popular than other equivalents. SA387 Grade 22 steel is under ASME SA387/ SA387M standard. The chemical performance and technical requirements of SA387 Grade 22 steel is almost same with ASTM A387 Grade 22 steel.

GNEE Steel also supplies a variety of boilers and pressure vessel steel plates, such as A204 Grade B,A515 Grade 70,A537 Class 1,SA387 Grade 11 Class 1,P265GH,S537 Class 2,P355Q,P275N,P355N,P690Q,Q345R, etc. If you want to know more about other types of steel plates, you can call the consultation hotline at +8615824687445 or send an email to alloy@gneesteelgroup.com.
