An analysis of the influence double normalization process on mechanical properties and microstructure 38MNVS6 steel

The aim of the article is to analyse of the impact the double normalization process of 38MnVS6 micro-alloy steel on the achievement of the required microstructure and selected mechanical properties. The analysis was made based on values of elongation at break and the criterion of the minimum permissible breaking work. The products used in the automotive industry were analysed. It were the forgings from 38MnVS6 steel in ball-shape and weights 28N forged at a temperature of 1250°C. It was shown that the double normalization process of 38MnVS6 steel was improved its microstructure and allowed on achieving the needs mechanical properties. The results shown in the work can be useful for other enterprises to achieve the effective processing of products, e.g. from the automotive industry.
