Product Code:SAE J405
Title:Chemical Compositions of SAE Wrought Stainless Steels
Issuing Committee:Metals Technical Executive Steering Committee
Scope:The chemical composition of standard types of wrought stainless steels are listed in Tables 1, 2, and 3. The 302XX series designates nickel-chromium manganese, corrosion resistant types, nonhardenable by thermal treatment (Table 1). The 303XX series are nickel-chromium, corrosion resistant steels, nonhardenable by thermal treatment (Table 1). The 514XX series, however, include both a hardenable, martensitic chromium steel (Table 2), and a nonhardenable, ferritic, chromium steel (Table 3). Table 4 lists proprietary and modifications of standard types to which elements have been added to provide special machinability characteristics. In order to avoid confusion with the AISI designations, the use of a suffix to denote a free machining steel or a variation in the carbon or silicon range has been retained. Therefore, the footnotes should be carefully followed. Reference to SAE J412 is suggested for general information and usage of these types of materials.
