This can be seen, for example, in a file blade for processing workpieces. 0000023466 00000 n 0000012976 00000 n Held at this temperature for a considerable time to ensure thorough penetration of heat at this temperature well inside the component and then allowed to cool separately by quenching in water oil or brine solution. 0000033299 00000 n 0000062478 00000 n In many cases, however, a high degree of hardness or strength is required. Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. 0000004052 00000 n 0000086899 00000 n Flame hardening / Induction hardening up to 11000 / 10 t Laser hardening 9500 x 5000 x 4000 Larger dimensions possible on request Through hardening dim. 0000068306 00000 n hardening and tempering Oct 27, 2020 Posted By Astrid Lindgren Ltd TEXT ID b23ae1cd Online PDF Ebook Epub Library Hardening And Tempering INTRODUCTION : #1 Hardening And Tempering * Book Hardening And Tempering * Uploaded By Astrid Lindgren, hardening and tempering heat treatment of steel in a school workshop is normally a two stage process for example if a high carbon steel or silver … primarily to increase ductility and toughness.
