Abstract
The spring industry has to process ultra-high strength spring strips of the steel grade 1.4310 (X10CrNi18-8). Springback during bending is a limiting factor for a resource-efficient production process in the so called stamping bending technology. This paper reports a mainly experimental investigation on the influence of bending parameters on the evolving springback of spring strips of the grade 1.4310 with tensile strengths TS = 1500-1800 MPa.
