Improper heat treatment of tool steels can lead to shorter tool life, higher incidences of metal fatigue, dangerous procedures, and expensive errors. To avoid these costly mistakes, leading expert Bill Bryson takes the mystery out of tool steel heat treatment by presenting a clear, practical approach to common techniques and applications. This easy-to-understand book is ideal for toolmakers, machinists, and engineers. It takes a comprehensive look at common heat treatment procedures used in shops around the world and provides detailed instructions for all types of tool steels.

The completely revised Second Edition of Metallurgy for the Non-Metallurgist provides a solid understanding of the basic principles and current practices of metallurgy. This major new edition is for anyone who uses, makes, buys or tests metal products. For both beginners and others seeking a basic refresher, the new Second Edition of the popular Metallurgy for the Non-Metallurgist gives an all-new modern view on the basic principles and practices of metallurgy. This new edition is extensively updated with broader coverage of topics, new and improved illustrations, and more explanation of basic concepts. Why are cast irons so suitable for casting? Do some nonferrous alloys respond to heat treatment like steels? Why is corrosion so pernicious? These are questions that can be answered in this updated reference with many new illustrations, examples, and descriptions of basic metallurgy.

Steel and its Heat Treatment: Bofors Handbook describes the fundamental metallographic concepts, materials testing, hardenability, heat treatment, and dimensional changes that occur during the hardening and tempering stages of steel. The book explains the boundaries separating the grain contents of steel, which are the low-angle grain boundaries, the high-angle grain boundaries, and the twinning boundaries. Engineers can determine the hardenability of steel through the Grossman test or the Jominy End-Quench test. Special hardening and tempering methods are employed for steel that are going to be fabricated into tools. The different methods of hardening are manual hardening for a small surface (the tip of a screw); spin hardening for objects with a rotational symmetry (gears with 5 modules or less); and progressive hardening (or a combination with spin hardening) for flat surfaces. The hardening and tempering processes cause changes in size and shape of the substance. The text presents examples of dimensional changes during the hardening and tempering of tool steels such as those occurring in plain-carbon steels and low-alloy steels. The book is a source of reliable information needed by engineers, tool and small equipment designers, as well as by metallurgists, structural, and mechanical engineers.

This book focuses on heat-treating by ASM, SME, and AISI standards. The manual has been created for use in student education, as well as to guide professionals who has been heat treating their entire lives. It is written without the typical metallurgical jargon. This book 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. Yes, 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. However, it also shows how proper heat and cryogenic processing can save your company money. Making money through longer life tooling, decarb-free and stress relief, all while learning how to create a better, finer grain structure. This manual shows the reader that hardness is only an indication of hardness, and that the real money savings is in the fine grained structure. This manual is written for toolmakers, engineers, heat-treaters, procurement, management personnel, and anyone else who is involved in metals. Metals are affected by the entire thermal scale from 2400�F, down to -320�F. That is the complete range of thermally treated metals and that is what this manual covers.
