Abstract
The article presents experiments aimed at increasing the properties of a plastic mould tool steel with a special heat treatment technology called shallow cryogenic treatment. Our chosen steel grade was Böhler M340 ISOPLAST. We would like to show how cryogenic treatment affects the wear and corrosion properties of this particular steel grade. We can conclude with tests and calculations that the cryogenically treated specimen showed at least 40% better wear and corrosion resistance properties, then the one treated with conventional heat treatment. Based on these findings, we expect that the tool life will also be longer using this heat treatment technology.
