ASTM A387 Plates

Most commonly used steel specifications for Chrome Moly plate are ASME SA387 and ASTM A387

Chemical and mechanical properties of the ASME and ASTM specifications are the same.

Gnee steel supplies Chrome Moly plates to ASME SA387 and ASTM A387 both from stock and, where required by the customer, cut to size and shape. SA387 and A387 are described as a “Standard Specification for Pressure Vessel Plates, Alloy Steel, and Chromium-Molybdenum.

Chrome Moly Plate
ASME SA / ASTM A387 Gr 11 Cl. 2, ASME SA / ASTM A387 Gr 22 Cl. 2, ASME SA / ASTM A387 Gr 5 Cl. 2, ASME SA / ASTM A387 Gr 9 Cl. 2.

Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength described as Class 1 and Class 2.

The most regularly specified grades and hence those that are most readily available from stock are Grades 12, 11, 22, 5, 91 and 9 and in most case stock plates will be produced to the tensile requirements of Class 2.

As with all ASME and ASTM pressure vessel steels, Chrome Moly to SA387 and A387 is produced in conformity to SA20 / A20 which outlines the testing and retesting methods and procedures, permissible variations in dimensions and weight, quality and repair of defects, marking, loading, and ordering information.

ASTM Pressure Vessel Steel Plate

What is Pressure Vessel Steel Plate?

Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures. Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant. There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methyl isocyanate. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.

In general these can be divided into three groups. There is a group of carbon steel pressure vessel grades. These are standard steels and can cope with many applications where there is low corrosion and low heat. As heat and corrosion have more effect on the steel plates chromium, molybdenum and nickel are added to provide additional resistance. Finally as the % of chromium, nickel and molybdenum increase you have highly resistant stainless steel plates that are used in critical applications and where oxide contamination needs to be avoided – such in the food and pharmaceutical industries.

The manufacture of pressure vessels is tightly regulated as a result of the risks involved and as a consequence the materials that can be used in vessels is also tightly specified. The most common specifications for pressure vessel steels are the EN10028 standards – which are European in origin – and the the ASME/ASTM standards which are from the US.

Our strength is in the very high specification pressure vessel  steel plate used in the oil and gas industry and specifically in steel plate resistant to Hydrogen Induced Cracking (HIC) where we have one of the largest stocks worldwide.

Standard:  A202, A203, A204, A285, A299, A302, A387, A515, A516, A517, A533, A537, A612, A662, EN10028-2, EN10028-3, EN10028-5, EN10028-6, JIS G3103, JIS G3115, GB713, GB3531, DIN 17155

Pressure vessel steel plate is used for many applications where the pressure inside is significantly higher than atmospheric pressure.

Pressure Vessel Steel Plate Applications:
  1. A516 steel plate is carbon steel with specifications for pressure vessel plates and moderate or lower temperature service.
  2. A537 is heat-treated and as a consequence, displays greater yield and tensile strength than the more standard A516 grades.
  3. A612 is used for moderate and lower temperature pressure vessel applications.
  4. A285 steel plates are intended for fusion-welded pressure vessels and plates are typically supplied in the as-rolled conditions.
  5. TC128-grade B has been normalized and used in pressurized railroad tank cars.
Other Applications for Boiler and Pressure Vessel Plate:
  • boilers
  • calorifiers
  • columns
  • dished ends
  • filters
  • flanges
  • heat exchangers
  • pipelines
  • pressure vessels
  • tank cars
  • storage tanks
  • valves

Classification Of Pressure Vessel Steel Plate

Pressure vessel steel plate

Pressure vessel steel plate covers carbon steel and alloy steel grades, which are designed for use in making pressure vessels, boilers, heat exchangers and any other vessels and tanks that to store liquid or gas at high pressures. It includes applications like below or similar:

  • Crude Oil Storage Tanks
  • Natural Gas Storage Tanks
  • Chemicals and Liquid Storage Tanks
  • Firewater Tanks
  • Diesel Storage Tanks
  • Gas Cylinders for Welding
  • Gas Cylinders for Cooking in peoples daily life
  • Oxygen Cylinders for Diving

There are a wide range of different liquid and chemicals that need to be stored under pressure.  Such us food, milk, plam oil, crude oil, natural gas includes their distillates to highly lethal acides which is bad to environments, so these liquid or gas shall be kept in high or low temperatures. Therefore, pressure vessel plates covers a wide range of steel grades which to use in different cases.

Carbon Steel Pressure Vessel Grades

Pressure Vessel Steel provides premium quality carbon steel plate for boiler and pressure vessel fabrication which is perfectly suited to the high standards set by the oil, gas, and petrochemical equipment, Octal stocks a wide range of dimensions of ASTM A516 GR70, A283 Grade C, ASTM A537 CL1/CL2.

Low Alloy Pressure Vessel Grades

The material grades that between pure carbon steel pressure vessel grades and stainless steel plates. Typically standards is ASTM A387, 16Mo3 these steels have improved corrosion and temperature resistance over the standard carbon steels but without the cost of stainless steels (due to their lower nickel and chromium content).

ASTM A516 PVQ STEEL PLATE

ASTM A516 is a PVQ carbon steel plate intended primarily for service in welded pressure vessels at moderate or lower temperatures, where notch toughness is important.
