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 ...

Grades 0, 1 and 2 are used in highly loaded gearing. Grades 1 through 4 are often used in rolling contact bearings . Greases with a higher number are firmer, tend to stay in place and are a good choice when leakage is a concern.
ISO 898 is an international standard that defines mechanical and physical properties for metric fasteners. This standard is the origin for other standards that define properties for similar metric fasteners , such as SAE J1199 and ASTM F568M . [ 1 ]
SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese , [ 1 ] with ...
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 is CDA 903
