The high-carbon steels require extreme care in the various heat-treating processes, and their use is discouraged by some on this account. The arguments advanced against its use appear to a skilled man without foundation, because men skilled in this branch of work can be had if they are given the necessary inducements. The higher the carbon the lower the critical point of the steel. If the operator bears this fact in mind he will have no trouble in determining the proper heats to employ in forging, annealing and hardening high-carbon steel. The idea entertained by some manufacturers that they must use a steel that fits the ability of their employees seems to be without proper foundation. It is better to use steel suited to requirements, and then employ workmen capable of properly treating it. The percentage of carbon is many times denoted by the term "temper." When used in this connection it has no association with the "letting down" process known as drawing the temper after hardening. The following table gives the uses of steel of various carbon contents as adopted by at least one manufacturing concern, and conforms very closely to general usage. It cannot be regarded as absolutely correct under all conditions, but answers as an approximate guide. orffi! Tools. 1.60 Tools requiring extreme hardness where toughness is not essential, for cutting partially hardened forgings, etc. 1.50 Turning hard metals, turning chilled rolls, etc. 1.40 Turning hard metals, corrugating tools, brass working tools and where a fine edge is required in connection with light cuts. 1.30 General tools for lathe work, cold...

Excerpt from Forge-Practice and Heat Treatment of Steel Modern demands 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 it has seemed wise to add to Forge Practice a certain amount of material devoted to the other branches of the art. 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 after all the most important factor is the man doing the work.
