Unified Numbering Systems for Metals and Alloys

50x50

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.
