As a simulation of the manufacturing of parabolic leaf springs a conventional heat treatment (CHT) and two variants of thermomechanical treatment (TMT) were applied on a group of CrV high strength steels, without and with Nb-microalloying. In a part of the steels the bulk concentration of phosphorus was increased above 0.02 %. The aim of the study was to determine fatigue properties for various tempering temperatures ∂ temp , especially of those steels contaminated with P. In a series of… CONTINUE READING
