Abstract: Subject of research: structure and properties of ball pins after heat treatment at various stages of metal processing. Purpose of the work: research and justification of economically alloyed steel for truck ball pins. Object of research: steering ball pin of a KAMAZ vehicle. Methods of research: for the manufacture of ball pins, 40X direct resistance steel (40X-PV) was used, smelted from metallized pellets at the Oskol Electrometallurgical Plant (OEMK). Determination of the content of basic substances in steels of electrical elements in accordance with current standards, using Spectrolab devices Iskroline-100 and a series analyzer and device GS-800. Main results of research: based on the study, the use of 40X steel to identify truck ball pins was justified. Technologies for plastic deformation and heat treatment of semi-finished products have been developed to ensure the desired texture and structure of tempered sorbitol. For volumetric quenching of workpieces, instead of MZM-16 oil, a quenching medium based on a water-soluble polymer was proposed, justified and introduced. The recommended solution, the implementation of ball pins for a KAMAZ vehicle, will provide an economic effect of more than 2 million US dollars. rub. and reduce the efficiency of their production.
