Evaluation of physico-mechanical properties of high-chromium tool steels modified with Harrington method

The qualimetric evaluation of high-chromium tool steels with application of modified desirability function was performed. It was shown that high qualitative performance was demonstrated by low carbon steels additionally alloyed with rare-earth metals, as well as optimally heat-treated steels. The methodologies for assessing the economic characteristics of high-chromium tool steels were proposed. The first technique is an assessment of the production cost of high-chromium tool steels in its early stages. The second technique is a value analysis of technological equipment, whose manufacturing needs high-chromium tool steels.
