TY - JOUR TI - Fatigue properties of fine-grained steels applied in components of semitrailers AU - Mazur, Magdalena TI - Fatigue properties of fine-grained steels applied in components of semitrailers AB - The article presents preliminary fatigue test results of selected grades of constructional steel used for producing elements of semitrailers and trailers, which are made by WIELTON S.A. company. Demand for fatigue tests of fine-grained steel has been reported by designers looking for new applications of high strength steel in new constructions. Fractorapnic analysis of the selected elements proved strong relation between fatigue structure and microstructure of the materials.
