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.

These are standard steels and can cope with many applications where there is low corrosion and low heat.

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. The plates are collectively known as Chrome Moly steel plates. 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.

Optimized workability

Roll-bonded shell plates, heads and cones in plain-carbon steel from a single source means optimum processing for our customers. The base materials are ideally matched during production. The large range of steel grades cover a wide spectrum of application possibilities.

Boiler construction and apparatus engineering

Creep-resistant pressure-vessel steels withstand even the highest temperatures in these areas of application. They are especially suited to use in hot-application pressure vessels

High-strength alloys

We supply high-strength CrMo- und CrMoV steels for the reduction of wall thicknesses in thick-walled pressure vessels. Our customers use the high-strength P460 NL2 mod grade for plates and heads in LPG tank trucks. Cryogenic 9%nickel steels with toughness down to minus 196 °C are used in the construction of storage tanks for liquefied natural (LNG) gas. We also supply heat-treatable fitting steels (WPHY) in as-rolled condition.

Greater thickness and sour-gas-resistant

We provide heavy shell plates in selected steel grades, in thicknesses up to 200 mm and higher unit weights up to 24 tons based on ingot-cast pre-material. We also manufacture pressure vessel steels in sour-gas-resistant design for our customers.
