The Unified Numbering System (UNS) for Metals and Alloys is an alloy identification system which was jointly developed by the ASTM International (formerly the American Society for Testing and Materials) and the Society of Automotive Engineers to provide a means of correlating many internationally used metal and alloy numbering systems administered by various societies, trade associations and

unified numbering system, Unified Numbering System for Ferrous Metals

The Unified Numbering System (UNS) for Metals and Alloys is established to correlate several internationally used alloy and metal numbering systems, which are now commonly used by trade associations, societies and producers and users of alloys and metals.

The Unified Numbering System (UNS) is an alloy identification system created in the early 1970’s and formalized with the issuance of joint standard ASTM E527 and SAE J1086 in August of 1974. The system assigns numbers to alloys on the basis of composition only. There is no definition of mechanical or other properties.

The unified numbering system (UNS) is an alloy designation system widely accepted in North America.Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property.

The Unified Numbering System (UNS) is the accepted alloy designation system in North America for wrought and cast copper and copper alloy products. The three-digit system developed by the U.S. copper and brass industry was expanded to five digits following the prefix letter C and made part of the Unified Numbering System for Metals and Alloys.

The SAE steel grade system’s correspondence to other alloy numbering systems, such as the ASTM-SAE unified numbering system (UNS), can be seen in cross-referencing tables (including the ones given below). Steel grades Chromium-vanadium steel 41xx steel SAE International American Iron

The unified numbering system (UNS) is an alloy designation system widely accepted in North America.It consists of a prefix letter and five digits designating a material composition. For example, a prefix of S indicates stainless steel alloys, C indicates copper, brass, or bronze alloys, T indicates tool steels, and so on.The first 3 digits often match older 3-digit numbering systems, while the

Metals and Alloys in the Unified Numbering System is a wonderful reference book for those of you working with metals and alloys. Here at Document Center Inc., we’ve often reached for it to help our customers when they have questions about what specs they should be using when there’s a reference to an UNS number in a contract.

The unified numbering system (UNS) uses a letter to designate a material category followed by five numbers constructed from the existing materials designations to coordinate all of these numbering systems. The unified numbering system (UNS) is described in Wikipedia at the link: Unified numbering system. Some of the category letters for steel are:
