Steel Division
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.
