STEELAR is aimed at two end-users with aligned needs:
Steel manufacturers like Sidenor, using rolls to produce steel products
Roll manufacturers such as Valji, producing the actual milling rolls
But the technology will also expand to other sectors:
STEELAR will also be applicable for evaluation of residual stress in rail tracks. Excessive stress levels both during manufacturing process or in-service represent a thread to the steel manufacturing sector and railway operators. One of the primary interests of ArcelorMittal by supporting this project is the potential application of STEELAR in rail tracks.
Gears for aerospace, naval and renewable Industries
Residual stress is a dominant factor in the fatigue performance of gear components. Compressive residual stress reduces the effective stress experienced in the gear tooth under a tensile applied bending stress. For gears, particular attention must be paid to the effect of surface treatments such as peening or induction hardening. The use of STEELAR´s surface penetration technology has the additional potential to be used for evaluation of gear tooth stress distribution.
Tubes and pipelines
One of the main reasons of appearance and growth of corrosion damages in oil & gas and nuclear pipelines transporting fluids is the process of stress-corrosion cracking of metal under the influence of residual tensile stress. The development of STEELAR technology will also allow for evaluation of surface stress levels in pipelines in order to prevent and mitigate corrosion induced failure.
