PoDoCo project pushed lightweight vessel forward
Ingrit Lillemäe-Avi investigated the fatigue strength of high strength steel with Meyer Turku under the PoDoDo program. The results show significantly improved fatigue strength of this innovative steel pushing lightweight vessel forward. Ingrit is now employed by Meyer Turku and continues the research work with the aim to introduce high strength steel in vessel structures.
Superior bendability of ultra-high-strength steels
The solution enabling the better formability and bendability of ultra-high-strength steels was developed in the DIMECC BSA program. The developed solution enables the utilisation of ultra-high-strength steels in new applications in which the utilisation of such steels was not possible earlier due to poor bendability of the steel. The outstanding properties of...
Virtual testing of steel ductility
In FIMECC BSA program VTT has developed together with Ruukki Construction and SSAB, acceptance criteria for new constructional high-strength steel grades. A new method to define the requirements for determination of material ductility parameters was described. The method was applied for the verification of local failure of structural parts with holes. The criteria developed...
High-performance steel solution enhances the quality of safety components in passenger cars

Enabling the use of ZnFe...
Ultimate protection with high-strength steels
Protolab Oy has developed a protected multi-purpose vehicle with advanced ballistic protection and mobility properties. The research conducted under FIMECC BSA program was in important role in the development work. The new vehicle fills a critical niche in the market.
High-strength steels enable novel lightweight marine structures
In FIMECC BSA program steel and shipbuilding experts joined their forces to develop novel lightweight marine structures. The utilisation of high-strength steels combined with advanced production technologies results in the weight reduction up to 20 percent bringing numerous advantages and rising competitiveness of Finnish shipbuilding industry.
Modern ultra high strength steels produced by direct quenching
Enhanced understanding on metallurgy and steel production processes was created in FIMECC LIGHT programme. This enhanced knowledge has enabled the widening of the dimensional ranges of new and existing products, and also enabled the design of new steel grades. In addition, the results generated in the FIMECC LIGHT programme serve as a knowledge platform on which future...
Enhanced manufacturing characteristics and tailored service properties through laser hybrid welding
Laser-arc hybrid welding can be simply described as a fusion-welding process where both a laser beam and welding arc are focused simultaneously in the same weld pool. This hybrid technology has a number of advantages, but in this context the most important is the use of external filler material to modify the metallurgical composition of the resulting weld. The objectives of...
New lightweight solutions for steel-based components reduces environmental footprint
New laser-welded lightweight sandwich panels for impact and wear resistant structures, and new lightweight panels for building industry were developed in FIMECC LIGHT programme. Benefits of new lightweight solutions are obtained over the whole life time of the product in terms of reduced energy consumption, reduced emissions and improved performance with integrated...
