Titanium Alloys International Cross Reference

Please find Titanium Industries Titanium cross reference metal equivalency chart below. There are many Titanium and designation standards that are used depending on countries, engineering practices, and many other standards. A description of each material standard can also be found underneath the Titanium equivalency chart.

UNS - International

UNS stands for Unified Numbering System and is a unified identification for metals and alloys of metals in the United States. Consisting of a single-letter prefix followed by five digits that represent material composition. Predominantly, the letter is suggestive of the family of metals identified.

DIN - Germany

DIN stands for Deutsches Institut für Normung eV (German Institute for Standardization). This standard uses the letters DIN, followed by alphanumeric codes or figures that represent the metals chemical composition, for designation of Titanium.

EN - Europe

EN stands for European Norms. This standard was mandated by the European Economic Community with the goal of standardizing common language on the European continent. Also created to replace national standards like BS - Great Britain, UNI - Italy, DIN - German, AFNOR - Frances, etc. These standards are still accepted and used by most countries, however.

AFNOR - France

AFNOR Stands for Association Française de Normalisation, which translates to "French Standardization". As the French organization for standardization, Alloy Steels are named using an alphanumeric system in which the first letter, A, designates the name of the element, and the following letters and numbers designate the alloying elements and their percentages.

JIS - Japan

JIS stands for Japanese Industrial Standards and are developed by the Japanese Industrial Standards Committee (JISC) in Tokyo. The specifications for designating Alloy Steels are pretty close to the ANSI/AA system. Beginning with the prefix JIS, followed by the letter A which denotes area of division, followed by four digits representing the composition of the material.

BS - Great Britain

BS stands for British Standards. This set of standards are developed by the British standard institute and uses alphanumeric characters to designate alloys. The letters in the designation represent the main alloying element and the figures represent the weight percent of the main alloying element.
