Stainless steel numbering system
The AISI maintained a numbering system for wrought stainless steel in which the three digits indicate the various compositions. The 200 and 300 series are generally austenitic stainless steels, whereas the 400 series are either ferritic or martensitic. Some of the grades have a one-letter or two-letter suffix that indicates a particular modification of the composition. In 1995 the AISI turned over future maintenance of the system to the Society of Automotive Engineers.
