What is AISI SAE numbering system?

Abstract: The SAE system uses a basic four-digit system to designate the chemical composition of carbon and alloy steels. … For many years, certain grades of carbon and alloy steels have been designated by a four-digit AISI/SAE numerical index system that identified the grades according to standard chemical compositions.

What is SAE material?

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.

What do AISI numbers mean?

The four-digit identification number used to designate carbon steel coils. AISI stands for the American Iron and Steel Institute. The first two digits in the AISI number indicate the grade of steel, while the last two digits give the amount of carbon in the steel.

What is SAE and AISI naming of steel?

The coding system is known for its efficient classification of steels as it uses the standards from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.). … Grades for alloy steels and carbon steels were identified by this system based on standard chemical compositions.
