STEEL
AMERICAN STEEL WORKER. By E. R. MARKHAM. This book tells how to select, and how to work, temper, harden, and anneal steel for everything on earth. It doesn't tell how to temper one class of tools and then leave the treatment of another kind of tool to your imagination and judgment, but it gives careful instructions for every detail of every tool, whether it be a tap, a reamer or just a screw-driver. It tells about tempering of small watch springs, the hardening of cutlery, and the annealing of dies. In fact there isn't a thing that a steel worker would want to know that isn't included. It is the standard book on selecting, hardening, and tempering all grades of steel. Among the chapter headings might be mentioned the following subjects: Introduction; the workman; steel; methods of heating; heating tool steel; forging; annealing; hardening baths; baths for hardening; hardening steel; drawing the temper after hardening; examples of hardening; pack hardening; case hardening; spring tempering; making tools of machine steel; special Steels; steel for various tools; causes of trouble; high speed steels, etc. 366 pages.

HARDENING, TEMPERING, ANNEALING, AND FORGING OF STEEL. By J. V. WOODWORTH. A new work treating in a clear, concise manner all modern processes for the heating, annealing forging, welding, hardening, and tempering of steel, making it a book of great practical value to the metal-working mechanic in general, with special directions for the successful hardening and tempering of all steel tools used in the arts, including milling cutters, taps, thread dies, reamers, both solid and shell, hollow mills, punches and dies, and all kinds of sheet metal working tools, shear blades, saws, fine cutlery, and metal cutting tools of all description, as well as for all implements of steel both large and small. In this work the simplest and most satisfactory hardening and tempering processes are given. The uses to which the leading brands of steel may be adapted are concisely presented, and their treatment for working under different conditions explained, also the special methods for the hardening and tempering of special brands. A chapter devoted to the different processes for Case-hardening is also included, and special reference made to the adoption of machinery steel for tools of various kinds. 4th Edition 288 pages. 201 Illustrations.
