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.
Keywords: high-chromium tool steels; alloying; heat treatment; the desirability function. |
