THE IMPORTANCE OF TEMPERING BY ELECTRONIC INDUCTION IN THE TREATMENT OF STEEL MATERIALS

Abstract

This paper discusses the importance of electronic induction hardening in the steel heat treatment process, emphasizing its evolution compared to conventional hardening. Traditionally, hardening aims to increase the hardness and surface resistance of materials, reducing wear. The induction technique is an efficient alternative, providing localized heating with less deformation and greater dimensional control. The objective of this study is to demonstrate the benefits of this process, through a case study at SKF do Brasil, comparing it to the conventional method. It is justified by the industry's need for faster, cleaner, more economical processes with less environmental impact. The methodology is based on a literature review, technical survey and analysis of data obtained from studies in industrial practice. The results showed that induction hardening allows excellent surface hardness without compromising the core, distributing residual stresses in a balanced manner, increasing the useful life of components. The comparison between the processes showed that induction generates less deformation and better mechanical performance in parts that require high wear resistance, such as gears, shafts and bearings. It is concluded that the induction tempering process stands out as a sustainable, precise and highly efficient technological solution, being fundamental for the modern industry that seeks to combine mechanical performance, economy and environmental sustainability.
