improving the process of achieving required microstructure and mechanical properties of 38mnvs6 steel

Abstract

The micro-alloyed steel 38MnVS6 (38MnSiVS5 or 38MnVS5) applied mostly in the automotive industry (for example production of forgings), has a high yield point and relatively good wear resistance. Aim of the study was preliminary to analyse the influence of twice the normalization process of micro-alloyed steel 38MnVS6 on its microstructure and mechanical properties. The normalization process was made in two steps in a pusher furnace PP-300 at temperatures 910 °C (cooling under the fan 5200 rpm) and 880 °C (cooling in open air). The total normalization time was 16200 seconds each time. Yield strength, tensile strength and hardness were analysed. Analysis was occurred based on results of the normalization process of three forgings for use in the automotive industry, ball-shaped and weight 28 N, forged from a temperature of 1250 ° C from micro-alloyed steel 38MnVS6. It has been shown that carrying out two processes for normalizing micro-alloy steel 38MnVS6 allows achieving its homogeneous and fine-grained microstructure and obtaining better mechanical properties and thus filled the gap regarding the lack of analysis of the impact of the normalization process on 38MnVS6 steel.

“…However, it also introduces new risks associated with corrosion [19,20] and biocorrosion [21], as well as joint fatigue [22,23] and wear [24,25]. The remedy for these problems lies in the proper selection of materials, both commonly used [26][27][28] and special alloys [29]. Their technological properties can be adjusted towards desired values by applying appropriate protective coatings [30][31][32] or modifying the surface layer [33].…”
