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. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system designated the AISI/SAE steel grades. In 1995 the AISI turned over future maintenance of the system to SAE because the AISI never wrote any of the specifications.

  • Stahlsorten sind die verschiedenen Arten von Stählen. Andere Bezeichnungen sind Stahlmarke oder -qualität; diese Bezeichnungen sind aber veraltet. Die Stahlsorten unterscheiden sich durch ihre vom Hersteller garantierten Eigenschaften, die durch unterschiedliche Zusammensetzung und thermische Behandlung erreicht werden. Die Bezeichnung für Stähle in Europa ist in der EN 10027-1 und 10027-2 festgelegt.Neben der simplen, aber abstrakten Klassifizierung nach erhält jeder Stahl noch einen , der sich hauptsächlich nach seiner Einsatzbestimmung richtet. Außerdem ist es üblich, Stahl nach seiner chemischen zu klassifizieren. (de)
  • La norma AISI/ (también conocida por ser una clasificación de aceros y aleaciones de materiales no ferrosos). Es la más común en los Estados Unidos. AISI es el acrónimo en inglés de American Iron and Steel Institute (Instituto americano del hierro y el acero), mientras que SAE es el acrónimo en inglés de Society of Automotive Engineers (Sociedad de Ingenieros Automotores). En 1912, la SAE promovió una reunión de productores y consumidores de aceros donde se estableció una nomenclatura y composición de los aceros que posteriormente AISI expandió. En este sistema los aceros se clasifican con cuatro dígitos. El primero especifica la aleación principal, el segundo indica el porcentaje aproximado del elemento principal y con los dos últimos dígitos se conoce la cantidad de carbono presente en la aleación (es)
  • 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. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system designated the AISI/SAE steel grades. In 1995 the AISI turned over future maintenance of the system to SAE because the AISI never wrote any of the specifications. Today steel quotes and certifications commonly make reference to both SAE and AISI, not always with precise differentiation. For example, in the alloy/grade field, a cert might say "4140", "AISI 4140", or "SAE 4140", and in most light-industrial applications any of the above is accepted as adequate, and considered equivalent, for the job at hand, as long as the specific specification called out by the designer (for example, "4140 bar per ASTM-A108" or "4140 bar per AMS 6349") is certified to on the certificate. The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard. 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). The AISI system used a letter prefix to denote the steelmaking process. The prefix "C" denoted open-hearth furnace, electric arc furnace or basic oxygen furnace, while "E" denotes electric arc furnace steel. A letter "L" within the grade name indicates lead as an added ingredient; for example, 12L14 is a common grade that is 1214 with lead added for machinability. (en)
  • La Society of Automotive Engineers (SAE) designa gli acciai grado SAE (SAE steel grades). Quattro cifre che rappresentano la composizione chimica standard per acciai. L'American Iron and Steel Institute (AISI) iniziò un lavoro simile. Una lettera è usata come prefisso per denotare il procedimento di fabbricazione. Il prefisso "C" denota Forno Martin-Siemens, Forno elettrico ad arco o Processo LD, mentre la lettera "E" denota Forno elettrico ad arco. Prima del 1995 la AISI fu coinvolta, e lo standard chiamato AISI/SAE steel grades. AISI fermò la collaborazione, nessuno standard fu mai pubblicato da parte sua. (it)
