Make innovation visible - Virtual product development of a brand new wire alloy with a reduced CO2 footprint

18 June 2024 | 

In the wire industry, voestalpine Wire Technology stands for excellent, customized wire solutions that meet and exceed even the most demanding requirements. Our modern R&D infrastructure and digital product simulations enable us to develop products impressively quickly and efficiently. Today, we are pleased to present the innovation of the 2023/2024 financial year that we are proud of. It includes a number of benefits for our customers.

Virtual product development as the key to success

The Research & Development department at voestalpine Wire Technology has been significantly expanded in recent years to give innovative product developments the space they need. These investments are bearing fruit, as our latest innovation shows: a virtual product development of a brand new wire alloy with a reduced CO2 footprint.

The development process

From the initial idea to the market launch, we used our state-of-the-art R&D infrastructure to develop the new alloy virtually. Steel development took place in the TechMet/MetLab, followed by wire development. Through trial rolling and various tests in the technical center wire, such as cold heading tests, relaxation tests and step-load tests, we were able to achieve the target values for the tempering properties and ensure that our new alloy meets the highest standards.

A new alternative upsetting quality with additional benefits

The innovation of the year 2023/2024 is the new development of an alternative upsetting grade to the standard material 42CrMo4. This customized steel alloy was developed virtually on the computer and offers significant advantages over 42CrMo4.

Particularly noteworthy is the direct formability without prior soft annealing, made possible by microalloying elements that form the finest precipitates and promote the ferrite content in the alloy.

Advantages of the new alloy:

  • Cost-efficient alternative: The new alloy is a cost-effective alternative to conventional Cr,Mo-alloyed QT steels such as 34CrMo4 and 42CrMo4.
  • Improved workability: Micro-alloying and thermomechanical rolling achieve high strength in the quenched and tempered condition.
  • CO2 reduction: The drawing process requires fewer annealing steps, resulting in a CO2 reduction of 200 kg per ton.
  • Wide range of applications: Particularly suitable for fasteners in the strength range up to 12.9.

Success has many faces

Project manager Katharina Ragger worked on this innovation in close cooperation with the University of Leoben, customers and application engineers over a period of three years. The first orders for concrete screw anchors for the construction industry have already been received, and other interested parties have expressed great interest.

The team has also been strengthened in terms of personnel: two graduates of Montanuniversität Leoben, Katharina Halwax and Stefan Monschein, made a significant contribution to the development and market launch of this CO2-reduced alloy and are now valuable members of our team.

The successful development shows the good cooperation across the entire value chain, from the idea to implementation and market launch, which was only possible by using the newly created research infrastructure.
