Forge-Practice and Heat Treatment of Steel. Originally published in 1904. Modern demand on the finished products of steel have necessitated rapid strides in the art of heat treatment of the metal. As the subjects of forging, hardening, tempering and annealing are so closely correlated, a certain amount of material devoted to the other branches of the art have been added to this edition of "Forge Practice" . The introduction of heat measuring and hardness testing instruments, together with various other modern appliances, and up to date systems of doing work have made necessary a broader knowledge of heat-treating methods than was formerly the case: for all the most important factor is the man doing the work. It is the wish of the writers of this volume that it may be instrumental in helping men engaged in heat treating steel to be of greater value to themselves and others. This book provides explanations which will aid in the production of work in an intelligent manner. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
