1- Metals Codes - Metals Standards
|Metals standards are industry wide agreements as to how metals are defined and expressed in a short code of numbers and letters. In this definition there may be information about the chemical composition, process of manufacture, heat treatment and many other pieces of hidden knowledge. The standard usually attempts to codify all of the various attributes into a simple to read letter/number designation. The ultimate utility of these standards is communication. Engineers, machinists, purchasing agents, and suppliers can all speak the same language of steel, aluminum, and copper and be assured of a consistent product..
Just as there are many different languages spoken on our planet, there are many different standards used around the globe. But even then foreign standards borrow heavily from or reply completely on United States standards.
