HARDENING, TEMPERING AND HEAT TREATMENT
In this valuable book Tubal Cain takes the reader beyond the superficial or the simply practical with explanations of the composition of steel, its additives, and the effects of different temperatures on its constituents.
With a grasp of what changes are actually taking place in the metal the care needed in following the practical processes described becomes understandable and will lead to better and more consistent results.
Flame, salt bath and furnace heating are detailed, with information on accurate measurement or recognition of temperature levels.
For the average small workshop operative or model engineer the discourses on tool material, hardening and tempering will be of most use, and in this connection this book replaces the earlier "Hardening and Tempering Engineers' Tools", providing a broader-based, more detailed and up to date examination of the subject!
Hardening high-carbon steel is easy - people have been doing it for thousands of years!
Just heat the metal to cherry-red and quench in cold water and there it is - hard! However, like the horse (which is ... a noble animal but does not always do so ...") this does not always work, and a little knowledge of what goes on inside the metal will both make failure less likely, and also give some idea of what to do when the occasional awkward job appears.
Those who find that horses never "do so" are always surprised how easy it seems when someone who knows about horses takes over! There is, they will say, nothing difficult about it -you just need to understand the animal.
It is the same with steel. Nothing difficult unless you are actually making the stuff, and that part is done for us. You may have a slight problem with some of the "new words"; these are explained as you go along, but you will also find a list at the end of the book to which you can refer if need be.
If "Know your Enemy" is prudent counsel for the soldier, then equally so must be "Know your Materials" for the engineer - model or otherwise. Important enough when the materials are to be cut or formed, but even more so when we propose to alter their characteristics.
So Tubal begins with a chapter on the makeup of steel and how it reacts to heat treatment and why. He offers no excuse for this initial exploration of the nature of iron and steel. You can "'skip" the chapter if you wish - it may be that it tells you nothing new, and could well seem to be irrelevant if all you want to do is to harden a scriber point!
But to begin at the beginning is always a sound policy, and there can be few such alterations so extreme as when we convert a relatively soft and ductile material into one which is hard enough to act as a cutting tool!
