Shipbuilding steel plates

Shipbuilding steel plates

Our shipbuilding steels in normal and high-strength grades are used in offshore applications, platform superstructures and for special ships in the oil and gas industry.

Areas of application

Steel shipbuilding plates are used in the cabin structures of cruise ships. The especially thin but wide plates are used for such applications to offer the best processing properties such as flatness and weldability. In contrast, high-strength, thermomechanically rolled shipbuilding plates are used in offshore applications. They are used for platform superstructures or for special ships in the oil and gas industry.

Safety and quality

We guarantee the highest safety and quality standards and meet all the requirements of renowned certification companies.

High-strength plates

High-strength plates made of fine-grained steel have a minimum yield strength of 620 and 700 MPa, and ultra-high-strength special grades achieve yield strengths of up to 1100 MPa.

Higher stresses

Machines and buildings are becoming ever larger. When you double the values of length, width and height of a component, the weight grows by a factor of 8, while the supporting cross-sectional area only grows by a factor of 4. This doubles the stress, which is calculated with the weight divided by the cross-sectional area. High-strength steels are capable of supporting these higher stresses and simultaneously lead to decreased weight of the component.

Specific advantages

The low weight of high-strength and ultra-high-strength heavy plates saves costs: The pre-material expenses, transport charges, and the assembly and foundation costs drop drastically. Add to that the costs saved during further processing of the material. Thanks to the excellent welding properties, work can proceed quickly and efficiently. On top of this, much less filler metal is required, and the weld seam test is simplified.

Our portfolio

We deliver high-strength heavy plates as fine-grained steels with a minimum yield strength of 620 and 700 MPa and ultra-high-strength heavy plates with a minimum yield strength of 900, 960 and 1100 MPa as special voestalpine grades.

Thermomechanically rolled fine-grained structural steel plates

alform®-steels are thermomechanically rolled steels with excellent weldability, toughness and cold-forming behavior.

We supply thermomechanically rolled heavy plates made of fine-grained steels with minimum yield strengths ranging from 355 to 550 MPa with exceptional toughness and the best welding and forming properties.

As a special high-quality voestalpine grade, alform® steels are found in structural steel work, bridges, pressure pipes and in vehicle and crane manufacturing.

Our thermomechanically rolled fine-grained steels are characterized by a high degree of toughness and excellent weldability. The low degree of cold cracking and high degree of toughness in the welding seam lead to a high degree of safety in welded structures.

Utilization of the higher yield strength in the high-strength fine-grained steels (alform plate 420 M, 460M, 500 M und 550 M), as opposed to the conventional S355, results in thinner cross sections that lead to cost savings through light-weight components and thus to less expensive transportation, assembly and foundations. Savings are also achieved in component manufacturing, particularly in welding.

Clad plates

Roll-bonded clad plates are the economic alternative to expensive high-alloy and non-clad plates. The mechanical properties of the base material are optimally combined with the corrosion resistance of the cladding material.

Our roll-bonded clad plates and heads are found in chemical equipment applications and refineries, in the oil and gas industry, coke drums and the food industry. Clad plates are also used in seawater desalination and flue gas desulfurization plants.

Materials

Clad plates consist of a base and a cladding material.

The base materials for our clad plates are produced exclusively in our own steelmaking plant in Linz. Cladding materials are purchased in the form of slabs and sheets from renowned manufacturers.

The base materials are predominantly made of structural steels, steels for boilers and pressure vessels and fine-grained structural steels, all of which are characterized by good weldability and formability.

Cladding materials are made of ferritic and austenitic stainless steels, nickel and nickel-based alloys, copper and copper-nickel alloys, all of which have excellent anti-corrosive properties.

Further material details are contained in the brochure that you can open below.

The base material surfaces are generally delivered in as-rolled or shot-blasted condition.

In almost all instances, the surface of the cladding material is polished. Our standard polish is 80 grain. Other grain sizes are available upon request.

Here you will find more information about delivery conditions and certifications for clad plates.
