STUDY OF STEELS FOR THE PURPOSE OF COMPARISON IN TERMS OF QUALITY INDICATORS AND ENERGY EFFECT OF THEIR PRODUCTION

Abstract

The main purpose of this work is to examine ingots of steel grades 35HGSL, GS-34CrMo4 and GS-42CrMo4 and to obtain data on the microstructure and mechanical properties in the cast state and after heat treatment. Based on the results, it is necessary to evaluate the effectiveness of the heat treatment used and possibly prove its justification, since this type of additional treatment is usually recommended to improve the quality of materials, but it is not mandatory, as in the present case. The economic costs of the manufacturer for conducting heat treatment can be a good solution only in the case of achieved better performance indicators of the materials, and the energy efficiency of the applied processes is essential. For all these reasons, as a result of researches will be created databases, which will give the opportunity to definite opinion on the problem.
