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 construction and apparatus engineering

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- 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.

From a single source 

 We supply from a single source shell plates, heads and cones made of both plain carbon steel and roll-clad design. This results in the following advantages for our customers:     

  • Manufacturing and processing benefits, primarily in the field of welding, through use of the same steel for shell plates and heads     
  • Technical consultation and coordination through quality assurance and research     
  • Simultaneous manufacturing and delivery of shell plates and heads     
  • Lower customer costs
