This online version ncludes 5,000 UNS numbers, 7,300 trade names and alloy designations, and 13,300 specification cross-references

What is UNS?
Jointly developed by ASTM and SAE, this new edition provides an overall designation system for thousands of metals and alloys in commercial use. The Unified Numbering System for Metals and Alloys (UNS) provides a means of correlating many internationally used metal and alloy numbering systems currently administered by societies, trade associations, and those individual users and producers of metals and alloys. To achieve the necessary uniformity for efficient indexing, record keeping, data storage and retrieval, and cross-referencing, this book is a MUST. The applicable specifications referenced include those from AA, ACI, AISI, AMS, ASME, ASTM, AWS, Federal, MIL, NACE, and SAE.
