Factors influencing hardenability of steels on the example of grade 42Cr MoS4. Convergence of the results of calculation and experimental methods

Abstract

This article identifies factors influencing hardenability of steels in manufacturing conditions of OJSC « BSW – Management Company of Holding «BMC». The article contains results of a study on dependence of hardenability of steel grade 42CrMoS4 on design features of the equipment and the process aimed to ensure correspondence of the fi al product to the requirements. Measures that minimize spread of values due to preparation of samples for hardenability test in industrial conditions are presented. When predicting hardenability band, it is necessary implement a package of application programs that consider influence of factors existing in the conditions of a particular steel manufacturer.
