Book excerpt: Excerpt from High-Speed and Carbon Tool Steels: Their Characteristics and Treatment Previous to 1909, each of the U. S. Navy yards prepared requisitions for the purchase of tool steels for its own purposes. These requisitions either specified that proprietary material should be purchased or that the award of contract be based on information obtained by a test of some description on samples submitted by the bidders. By this method, there could be no uniformity in the specifications of the navy yards, and in order to centralize purchasing and to standardize the tool' steels, a tool steel board recommended that the Philadelphia Navy Yard be made the purchasing station. This action was taken in 1909 and at that time specifications were drawn up for one high-speed steel and three grades of carbon steel. The chemical composition required for the high-speed steel differed from that of any of the commercial brands, but the chemical composi tion of each grade of carbon steel corresponded to that of commercial tool steels. The three grades of carbon tool steel varied principally in their carbon content, in order to adapt them to the purposes for which such tool steels are generally used. The contracts were awarded to the lowest responsible bidder who was able to meet these specifica tions for tool steel of a chemical composition within the specified limits. The specifications required physical tests in addition to chemical analysis, as a part of the inspection, but these tests did not give decisive results and proved conclusively that it was advisable to revise the existing specifications. This step was taken because these specifications did not provide a means of ascertaining the relative merits of the tool steels offered by the different bidders, or of learning whether there were other tool steels that were superior to those within the specified limits of chemical composition.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from High-Speed Steel: The Development, Nature, Treatment, and Use, of High-Speed Steels, Together With Some, Suggestions as to the Problems, Involved in Their Use The entire subject is so recent, however, and astonishing developments have followed one another with such bewildering rapidity, that the aecom plishing of this purpose presented many difficulties. Almost every steel man knows the practical impossibility of obtaining detailed information concem ing tool steels which is absolutely accurate and reliable. The personal equation and a multitude of other factors commonly accounted negligible, so much affect results that the assertion might be safely hazarded that all conclusions as to method and means in steel treatment are subject to allowances for these elements. Thus, for illustration, two different plants operated by the some concern make large use of the barium process in hardening. At one the temperature commonly maintained and indicated by the pyrometer is 1200 degrees C. (2200 while at the other an instrument of the same make and calibrated with equal care uniformly indicates only 1070 degrees C. (1950 F.) and yet as far as can be seen by the eye of an experienced operator, familiar with both plants, the two baths are kept at identical temperatures. Certain it is that results equally good are obtained at both plants. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Tool Steels, Data and Tables Appertaining to Electric Tool Steels Factors affecting qualities OF steel. Chemical composition, method of manufacture, mechanical treatment in shaping and heat treatment before use, are all factors of importance in developing maximum serviceability in steel. Service failures may be due either to improper manufacture or to improper treatment after manufacture. Since the chemical composition, the method of manu facture and much of the mechanical treatment are factors that rest with the steelmaker, it is obvious that to produce the best steel for any particular use requires adequate and proper facilities and skill in manufacture.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Ludlum Steel Company: Carbon and Alloy Tool Steels The crucible process is one of the oldest methods of making high grade steel. The product is governed by the raw material used, therefore even though the highest form of Skilled control be applied to the melting and working of this steel, it is of no avail if the raw material contains some unlooked for im purities. That is one of the reasons why various melts of crucible steel, made from the same high grade raw material, differ very largely in their work and efficiency. The Ludlum Steel Company, recognizing this very serious defect in the highest grade crucible steel, started to investigate methods of melting wherein full refining could be accomplished, the crucible process being purely one of remelting.

This book was released on 2018-02-05 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Relation of the High-Temperature Treatment of High-Speed Steel to Secondary Hardening and Red Hardness The metallography of high-speed tool steel presents certain anomalies, the explanation of which is not clear from the usual conceptions of the mechanism of hardening in simple carbon steels, as, for example, the familiar polyhedral structure of prop erly quenched high - speed steel, which is often called austenite, although its physical properties are largely those of martens-ite. The explanation of such anomalies and a better understanding of the fundamental nature of high - speed steel is becoming more and more important as the peak of its development is being reached. It is even probable that future improvements will be largely in the technique of treatment and the adjustment of compositions to meet special requirements, in which cases fundamentals are of highest importance.
