This is the 20th Anniversary Edition of this well-known standard reference publication. This latest edition incorporates the many changes in the specifications and designations of irons and steels that have occurred over the past six years. It also covers more countries, more alloys, and more standards than previous editions, while keeping obsolete designations for those persons trying to duplicate equipment from old documents. Key Features: This latest edition of the guide has been organised in the same popular way as the previous edition. The primary organization is based on the type of iron or steel. The main divisions within this framework are: Cast Irons, Cast Steels, Cast Stainless Steels, Alloy Steels, Carbon Steels, High-Strength Steels, Wrought Stainless Steels, Heat Resistant Steels, and Tool Steels. These major divisions are further divided into common groups, and then individual alloy listings. In listing the individual alloys, similar alloys from international sources have been grouped together. Description: This comprehensive guide presents detailed descriptions of the many individual ferrous materials that are available throughout the world. These descriptions, however, have been organized in a clear and concise way. Thus, the guide can be used as the starting point for global sourcing of equivalent materials from amid the confusing multitude of ever-changing standards and designations. Contents: The listing for each individual irons and steels includes country of origin cognizant standards organization relevant specification alloy designation description of the material, including temper/condition and product forms chemical composition ultimate tensile strength, yield strength, and elongation. Also included are complete indexes of standards and designations, and a handy listing of national and international standards organizations.
