Pressure vessel plates

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 and apparatus construction

Pressure-vessel steels made by voestalpine Grobblech GmbH are found in the equipment and boilers in the chemical and petrochemical industries. 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 and 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.

From a single source 

 We are a single-source supplier of shell plates, heads and cones in carbon steel and in roll-clad condition. The main benefits for our customers are as follows:

  • Advantages in processing technologies, especially during welding, based on use of the same steel for shell plates and heads
  • Technical consultation and coordination provided by quality and research specialists
  • Simultaneous manufacturing and supply of shell plates and heads
  • Lower procurement costs for our business partners
