The Belgian Nuclear Research Centre SCK CEN developed a family of affordable low-activation steel grades that demonstrates superior properties to EUROFER97 (reference material in Europe for plasma-facing components in fusion applications).
Its larger ductile range, higher strength and higher creep resistance offer a strong alternative/upgrade to EUROFER97 and can be applied in other applications for components requiring very high ductility (i.e., pipes) or very high strength (i.e., supporting plate/stiffening boards). The material’s thermo-responsive traits allow post-production property adjustments, broadening its utility. In extreme heat scenarios, its microstructure changes predictably, beneficial for safety-critical structural assessments.
