Abstract
EN The following article compares three different hot forming tool steels with regard to their wear. The selection of the right material has a significant impact on tool life and, therefore, on the cost of manufacturing products. The steels examined were WCLV, Uddeholm Unimax and Uddeholm QRO 90 Supreme. First of all, the hardness of the materials was tested using a Vickers hardness tester and the chemical composition using an X-ray fluorescence spectrometer. Wear tests were also carried out on a ball-on-disc tribometer to compare the mainly abrasive wear of the materials under laboratory conditions. The wear of the selected steels was also compared under real conditions. For this purpose, punches were used to forge a batch of products, followed by comparing the signs of wear and the structure of the surface layer using an optical profilometer. The tests carried out show that WCLV steel has the lowest wear life of the materials tested, with the highest wear during the tests. In contrast, Uddeholm Unimax steel showed the best results, with the highest hardness and the lowest coefficient of friction and volumetric wear in the tribological tests.
