COOPHS in a nutshell
Enhancing low CO2 steel production for the automotive sector through the development of more sustainable processing methodologies
ABOUT THE PROJECT
The COOPHS project focuses on evaluating how eco-friendly steel processing affects the performance of ultrahigh strength Press Hardened Steels (PHS). By delving into the influence of residual elements in press hardening steel, the project seeks to enhance low CO2 steel production for the automotive sector, ultimately advancing the industry’s environmental and technological standards by minimising CO2 emissions.
During the project, the impact of residual elements from EAF steel production routes on microstructures and subsequent material properties will be examined. The project also aims to determine segregation effects on critical properties, design a tool for emissions-product compromise to facilitate the progression of low CO2 steels in the PHS automotive market, compare EAF and BOF-based solutions, and propose optimized low emission processing routes.
This initiative aims to advance both environmental sustainability and the European steel market’s competitiveness, in line with RFCS Research programme objectives and the European Green Deal Roadmap.
Key Data

Environmental-Performance Equilibrium
Identification of the optimum compromise of CO2 emission levels and product and application performance of ultrahigh strength press hardened steels.
COOPHS EXPECTED RESULTS
The COOPHS project is to deliver outcomes through cutting-edge research and innovation. The project is set to provide results contributing to a more sustainable future of steel processing:
Deeper insight into residual element impact on PHS microstructures
Quantified local residual element concentrations in microstructures.
Enhanced understanding of PHS mechanical property effects.
Development of a tool for CO2 emission-product compromise in automotive sector.
Comparative analysis of EAF vs. BOF steel solutions.
Optimised low emission processing routes for high-performance steels.
PROGRESS BEYOND THE STATE OF THE ART
Enhanced Compatibility of Automotive Press Hardened Parts
State of the art: Initial insights from literature and lab tests revealed that PHS have potential ductility risks in martensitic parts due to residual elements.
COOPHS contribution: The project aims to establish a direct link between residual element content and mechanical behaviour in press hardened steel. This understanding pave the way for countermeasures to mitigate associated risks and ensure compatibility with automotive safety standards.
Optimized Press Hardening Processes
State of the art: Exploration of alternative steel manufacturing methods demonstrated promising results within the standard hot stamping process parameters.
COOPHS contribution: The project will focus on non-BOF steel manufacturing methods, adapting hot stamping processes and parameters accordingly. This advancement could ensure the attainment of required results and offers insights into parameter optimization for superior property outcomes.
Quantification of Solute Segregation at Grain Boundaries
State of the art: Insights from existing literature emphasized the significance of solute segregation at grain boundaries during heat treatments.
COOPHS contribution: The project aims to unravel the intricate effects of solute segregation on steel properties. This newfound knowledge will enable a comprehensive assessment of acceptable solute quantities concerning industrial deployment and product risk evaluation.
Advanced Analysis of Coated PHS Interfaces
State of the art: Previous research highlighted the potential of FIB+APT technique for analysing interfaces like oxide/Fe or Zn/Fe.
COOPHS contribution: The COOPHS project will go beyond by successfully adapting this technique for complex Fe/Al interfaces in coated PHS. This innovative approach enables safe quantification of intricate soft/hard coating/substrate interfaces.
