Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars ( ASTM A276 ) or stainless steel plates for pressure vessels ( ASTM A240 ) or pipes ( ASTM A312 ).
All substances must be declared in the material data sheet (MDS) of the IMDS to a resolution of 1 gram or better – not just declarable and prohibited substances (e.g. Cr VI / Hg / Pb / Cd). Substances and materials of products must be known in detail so that it may be delivered by the OEMs to dismantler companies in order to achieve the goals ...
A heat number is a unique identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill. It serves as a traceable identifier that links the metal product to its specific batch or "heat," allowing access to detailed records about the material's composition, manufacturing process ...

A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single ...
The system is a catalogue of specifications in the English language, to allow buyers to purchase standardised materials all over the world. When MESC was initially introduced, materials were allocated a unique 7-digit number. This was increased to ten digits in 1946. [1] The system has a numerical "coding schedule" of 10 digits to code the ...
Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
