Metals and Alloys in the Unified Numbering System (UNS): 12th Edition DS56K

The UNS for Metals and Alloys provides a means of correlating many internationally used metal and alloy numbering systems administered by societies, trade associations, and individual users and producers of metals and alloys. Jointly developed by ASTM International and the Society of Automotive Engineers (SAE), it provides the uniformity necessary for efficient indexing, record keeping, data storage and retrieval, and cross-referencing. The 12th edition has been updated to include more than 5,600 designations, 4,100 representative specification cross references, and 15,350 trade names. This edition includes:
Introduction

Index to UNS Designations by Base Elements

Listing of UNS Numbers assigned-to date, with a description of each material covered and references to documents in which the same or similar materials are described

Cross-index of commonly known documents which describe materials which are the same as or similar to those covered by UNS numbers
