durostat®

Superior solutions

Made of wear-resistant steel

Highest wear resistance and hardness for the highest stresses Just like a diamond, our durostat® steels stand for highest hardness. This special property of our durostat® steels is the reason for their essentially higher resistance to wear than conventional steels. They are optimally suited to applications with high mechanical stress and high levels of abrasion. Our durostat® steels also guarantee excellent toughness at low application temperatures.

Our customers are found in the petrochemistry, oil and gas, paper and pulp, energy and railcar manufacturing industries. We are the world's only single-source supplier to deliver shell plates, heads and cones made of carbon steel in clad design.

Our materials

We use structural steels, fine-grained structural steels and pressure-vessel steels for carbon-steel heads and pressed parts.

We manufacture clad heads and pressed parts from all conventional carbon steels. We supply stainless and heat-resistant steel grades and non-ferrous metals and alloys as cladding materials for optimum corrosion resistance.

Chords

High-strength heavy plates are found in offshore platform applications. We use a special tool in the head press shop to hot-form parts used in offshore platforms.

Support and anchoring system

Offshore platforms are supported by adjustable feet. During ocean transport, the feet are retracted and point upwards. At the designated location, the stands are extended until they reach the sea floor. Chords made by voestalpine Grobblech strengthen the gear racks of the feet and allow safe operation in rough conditions.

Complex manufacturing process

We developed our manufacturing technology for chords as hot-formed parts in our in-house press shop. The pre-material is heavy plate of high-strength fine-grained structural steel from our own rolling mill. Strips are cut from this plate and formed into chords with a special tool on a hydraulic press with a maximum pressing force of 3,500 tons. The tool function is based on finite-element calculations and guarantees a high degree of accuracy to shape. After being hot-formed, the chords are water-quenched and straightened. The edges are flame-cut and milled on both the side and end faces.

Heavy plates made of case-hardening and heat-treatable steels

Case-hardening and heat-treatable steels are usually heat-treated following final processing at the customer in order to unfold their final properties. Typical areas of application are in making tools and molds.

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.

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.

Wear-resistant plates

Our durostat® and altrix® are attractive special grades for applications that require a high level of wear resistance.

Parts used in abrasive environments wear out quickly. In order to lengthen the service life of such components, we have developed two special steel grades whose service life is significantly longer than that of conventional steels. Our online-hardened durostat® carbon steels are especially wear-resistant and demonstrate the best processing properties. Our highly wear-resistant altrix® steels include multi-layer plates for an even longer service life.
