Innovation & insights

The disc spring is the unsung hero of the seven seas. This small but vital component helps protect people, goods and ships in some of the harshest conditions imaginable. It’s also a powerful example of Alleima’s innovative capabilities in developing advanced steels built to withstand life at sea.

Medical implants in orthopaedic, cardiovascular, and dental applications face extreme conditions inside the human body, constant mechanical loads and a chemically aggressive environment.
To remain safe and reliable over a patient’s lifetime, materials must be biocompatible, stable, strong, fatigue- and corrosion-resistant, and highly durable. Failures can lead to fractures, wear debris that causes inflammation, or corrosion that releases harmful ions.
We develop high-purity stainless steels engineered to meet these demands and ensure long-term implant performance.

Alleima attended this year’s Hydrogen Technology Expo Europe in Hamburg, and the conversations across the exhibition floor reflected an industry at a crossroads. While the excitement surrounding hydrogen’s rapid scale-up has eased since its early peak a few years ago, there’s now a more mature, focused approach emerging, one that prioritises cost efficiency, technical reliability, and project realism.

Around the world, including in the East Asia and Pacific area, steel manufacturers face significant pressure to reduce emissions from original equipment manufacturers (OEMs), regulators, and consumers. The rise in life cycle assessment is a testament to this increased focus.

For hard-to-abate industries like steel, reducing emissions and increasing the sustainability of material manufacturing processes is critical.

Surgery is one of the foundational pillars of modern medicine. Each procedure demands precision, not only from the surgeon’s skill, but also from the instruments in their hands. We know that the quality and reliability of these instruments start with the steel they are made from.

Defects such as burrs and cracks can compromise safety, function, and longevity. That’s why the purity, hardness, and corrosion resistance of the steel play a decisive role in both patient safety and surgical success.

On 25 September 2025, engineers, specialists, and decision-makers from across the oil and gas supply chain joined Alleima’s exclusive Alloys for Oil & Gas Application Seminar 2025 in Rio de Janeiro.

The steel industry is a cornerstone of global infrastructure, but it also comes with significant environmental challenges. Today, the industry accounts for around 8% of global energy use and 7% of CO₂ emissions. We are, however, at the heart of an exciting transformation, where sustainable initiatives are reshaping the industry with low-carbon technologies, improved resource efficiency, and greener products.

These hidden heroes are driving smarter, lighter, and cleaner solutions, from hydrogen fuel cells to high-performance machinery.

Thermal spraying is an advanced manufacturing method in which material in powder or wire form is melted and sprayed onto a surface to create a coating with specific properties. Alleima is now investing in this technology to develop new products in the field of sustainable energy. For example, the technology can be used in the production of components for green hydrogen through electrolyzers. Alleima is already in dialogue with several interested customers, and the first prototype of the coated material has already been sent to a customer.

At Alleima's Annual General Meeting in Sandviken, the Innovation Prize 2025 was awarded to Thomas Froböse, Chief Technology Officer, and Haydn Eagle, Sales Manager, both from business unit Specialized in the Tube division. They received the prize for their exceptional contribution to a critical component in the steering module of a space application. The component for a rocket exemplifies outstanding innovation and engineering excellence as the material had to withstand very high temperatures in combination with high pressure.

New steel characteristics are required for the electric compressors that will power car air conditioners in electric vehicles. Teru-aki Watanabe at Alleima explains why.

At Alleima, we have been leading advancements in knife steel for decades, optimizing the metallurgical properties that define performance, durability, and customization.

Alleima will supply Preem with heat exchanger tubes to be used in the conversion of the Lysekil refinery from fossil to renewable fuels. The investment is an important part of Sweden's green energy transition and will make Preem the largest producer of renewable jet fuel in northern Europe.

Alleima Guru, the generative AI solution of Alleima, enables researchers to develop new hypotheses thanks to instant access to the company’s 60,000 research reports. Reports are generated from 160 years of research.

Sandviken-based Alleima, a global manufacturer of high-value-added stainless steel and special alloys, has today signed an agreement with KTH. The partnership aims to deepen collaboration in research and education, enhance scientific excellence, strengthen societal benefits, and increase innovative capacity in addressing the major challenges faced by society today.
