ESP 65 was developed as a special case-hardening steel for state-of-the-art processing technology:

ESP 65 is a special case-hardening steel that was developed for use with modern machining technologies. ESP 65 is the case-hardening steel from Steeltec that can help you rationalize your production processes, improve product quality and generate long-term cost savings. The advantages of using ESP 65 really come to the fore when turned parts that require substantial amounts of machining or that have an asymmetric geometry need to be manufactured cost efficiently. Its excellent machinability results in shorter processing times and longer tool lives.Steeltec adjusts the structure of the steel to produce a a case-hardening steel with a very uniform and homogeneous microstructure. The result: lower process costs and increased productivity. Our case-hardening steels are used to manufacture spindles and gear parts for power drills, angle grinders and other power tools, as well as mirror adjusters, pump components and shafts for the automotive sector.
