Unified numbering system
The unified numbering system 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 last 2 digits indicate more modern variations. For example, Copper Alloy No. 377 in the original 3-digit system became C37700 in the UNS System. The UNS is managed jointly by the ASTM International and SAE International. A UNS number alone does not constitute a full material specification because it establishes no requirements for material properties, heat treatment, form, or quality. Some common materials and translations to other standards: UNS K11547 is T2 tool steel UNS S17400 is ASTM grade 630, Cr-Ni 17-4PH precipitation hardened stainless steel UNS S30400 is SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel UNS S31600 is SAE 316 UNS S31603 is 316L, a low carbon version of 316
