Knowledge platform on high strength austenitic stainless steels
World-class knowledge platform on high strength austenitic stainless steels was created in FIMECC LIGHT programme. The knowledge generated serves as a platform on which new generations of ultra-high-strength stainless steels will be developed.
Multi-scale modeling links the microstructure to wear performance
The wear behavior of high strength steels and metal matrix composites was investigated by way of microstructure based multi-scale modeling. The multi-scale modeling and simulation approach enables to establish links between material microstructure and its properties, microstructure and wear performance, as well as to produce methods for understanding and quantifying the...
New wear test devices narrow the gap between research and practice
Experimental research plays a key role in solving wear problems. The following four novel wear test devices were developed in the DEMAPP programme: a dual pivoted laboratory jaw crusher, an impeller-tumbler impact-abrasion tester, a high-speed slurry pot tester, and a high velocity particle impactor (HVPI) for wear model and simulation validation. The test devices were...
Fretting damage prediction for highly loaded machine components
Fretting fatigue, i.e. decreased fatigue performance due to the small oscillatory movement between contacting bodies, is often considered as the plague of modern industry. A novel modelling and experimental methods has been developed and successfully applied in diesel engines in order to optimize and increase safety margin to fretting damage.
Material efficient blast furnace
Material efficiency of iron making was improved by the project dramatically and the usage of virgin raw material was decreased significantly. The achieved result improve the cost efficiency and sustainability of steel production.
Advanced steelmaking through digitalisation of physical phenomena
Digital models revolutionizes steel developing. By simulators you can see virtually inside the steel making process. This allows you to watch the steel making process, test different parameters and practices and predict the exact grade of steel. The steel converter simulator saves time and money by accelerating time to market, decreasing slag and carbon dioxide emissions,...
Seeing inside of steel - Improving steelmaking with new simulators
Novel comprehensive simulators developed take steel design to new digital era. This means improved quality, increased productivity, cost efficiency and yield. Simulators also able new steel grade development decreasing time to market and and reducing the need for production trials with significant carbon dioxide emissions.
Novel corrosion resistant stainless steel without nickel
High-chromium ferritic stainless steels with good corrosion resistance and formability have been developed for demanding applications. Independent of the high and fluctuating price of nickel these novel ferritic steels provide cost-efficient alternative to current austenitic grades. Based on wide research and pilot-scale development the first 21% chromium grade have been...
Raex wear-resistant and ultra-high-strength steels
Key enablers for a complete family of new wear-resistant and ultra-high-strength steels were developed. Utilizing Ruukki’s own direct quenching technology the new steels bring energy efficient, light solutions for transportation as well as safety and new performance for harsh crushing and mining applications.
