Cover Story
Alleima’ s materials are increasingly being developed not just for technical performance, but for long-term sustainability.
• All operations are powered by approximately 96 % fossil-free electricity.
• And its materials directly support sectors like renewables, hydrogen transport, carbon capture, and waste-to-energy.
This ethos is shaping both existing and emerging product lines.“ The green transition is not just a trend, it’ s a structural shift,” says Eleonora.“ We’ re designing alloys specifically for the hydrogen economy, for corrosive clean-energy systems, and for energy-efficient operations.”
Material breakthroughs that matter Innovation at Alleima is visible in its portfolio of breakthrough alloys, many of which were developed and refined through in-house R & D over the last decade. One standout is Sanicro ® 35, a high-performance austenitic stainless steel that bridges the gap between standard stainless steels and nickel alloys.“ Sanicro ® 35 offers excellent corrosion resistance in both acidic and chloride environments, while being more cost-effective than nickel-based materials,” says Daniel.“ It’ s a game changer for many heat exchanger applications.” Newer additions to the product family include:
• SAF™ 3006, a super duplex stainless steel tailored for heat exchanger applications in acidic and alkaline conditions. It combines excellent general corrosion resistance with high mechanical strength.
• SAF™ 3007, developed for the umbilical industry, where extreme strength, chloride resistance, and production robustness are required.
“ These are materials that push the envelope,” Daniel continues.“ But they’ re also designed to be userfriendly in production and fabrication, which is what we call‘ forgiving materials.’” Also on the near horizon is the launch of SAF™ 2906, a proven long-standing material for the urea industry. While the grade itself is not new, its availability for this critical chemical sector is a strategic expansion of Alleima’ s offering.
Digital modelling, AI, and accelerated development One of the company’ s biggest R & D strengths is its sophisticated use of digital tools, particularly in alloy design and knowledge retrieval. Before even casting a new alloy, the team uses advanced simulation software to predict alloy
