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. These efforts were similar ...
SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1] The name comes from the chemical makeup which is approximately 17% chromium and 4 ...
304 stainless steel is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for vaporizers. Early SpaceX Starships used SAE 301 stainless steel in their construction, [8] before moving over to SAE 304L for the SN7 test tank [broken anchor] [9] and Starship SN8 in 2020. [10]
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
UNS K11547 is T2 tool steel; UNS S17400 is ASTM grade 630, Cr-Ni 17-4PH precipitation hardened stainless steel; UNS S30400 is SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel; UNS S31600 is SAE 316; UNS S31603 is 316L, a low carbon version of 316. The digits "03" were assigned since the maximum allowed carbon content is 0.03%; UNS C90300 ...
