This indispensable manual focuses on heat-treating by ASM, SME, and AISI standards. It has been created for use in student education, as well as to guide professionals who have been heat treating their entire lives. Written without the typical metallurgical jargon, it will serve as a training manual from day one in learning how to heat treat a metal, and then also serve as a day-to-day reference for a lifetime. This manual zeros in on the popular tool steels, alloy steels, heat-treatable stainless steels, case hardening steels, and more. It deals with these metals with up-to-date usage and processing recipes. What is different with this manual from all the others is that it doesn't just deal with the heat-treatment process, it also covers the continuation of the hardening process with cryogenics. It is written to help those who may want a thorough understanding of what goes on in the process of heat-treating and how to do it better. It also shows how proper heat and cryogenic processing can save your company money through longer life tooling, decarb-free and stress relief, all while learning how to create a better, finer grain structure. This manual shows that hardness is only an indication of hardness, and that the real money savings is in the fine grained structure. Written for toolmakers, engineers, heat-treaters, procurement, management personnel, and anyone else who is involved in metals, this manual covers the complete range of thermally treated metals from 2400 F down to -320 F.
