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 

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.

HICfit pressure vessel plates for sour service

The voestalpine product family HICfit stands for pressure vessel plates for sour service and is characterized by their excellent resistance against hydrogen induced cracking (HIC).

HICfit heavy plates are made of slabs produced in our own steel plant. All measures to ensure highest cleanliness of steel are applied during production. This especially includes steel making via the LD process, originally invented and optimized by voestalpine, and the state of the art soft reduction process during continuous casting.

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

voestalpine unsere Antwort auf Korrosion

Our answer to corrosion

Clad plates are the economic alternative to expensive high-alloy and non-clad plates. Roll-bonded clad plates are our answer to corrosion and explosion. 

With a cladding capacity of 60,000 tons a year, we are World´s leading producer of roll-bonded clad plates.

Broad range of expertise

We supply steel plates and material expertise for the penstocks of hydro-power stations and provide high-strength heavy plates as fine-grained steels with a minimum yield strength of 700 MPa in TMCP, direct-quenched and tempered or quenched and tempered condition. 

In a first-time application of high-strength TMCP steel, special-grade alform plate 700 M of voestalpine was successfully used in the penstock of the Reisseck pumped-storage hydro-power station in Austria.
