SAE 304 stainless steel is the most common stainless steel. It is an alloy of iron, carbon, chromium and nickel. It is an austenitic stainless steel, and is therefore not magnetic. It is less electrically and thermally conductive than carbon steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]
The composition was developed by W. H. Hatfield at Firth Brown in 1924 and was marketed under the trade name "Staybrite 18/8".[2]
It is specified by SAE International as part of its SAE steel grades. It is also known as:[3]
- 4301-304-00-I and X5CrNi18-9, the ISO 15510 name and designation.
- UNS S30400 in the unified numbering system.
- A2 stainless steel outside the US, in accordance with ISO 3506 for fasteners.[4]
- 18/8 and 18/10 stainless steel (also written 18-8 and 18-10) in the commercial tableware and fastener industries.
- SUS304 the Japanese JIS G4303 equivalent grade.
- 1.4301, the EN 10088 equivalent.[5]
- 06Cr19Ni10 and ISC S30408, the equivalent in Chinese GB/T 20878 and GB/T 17616 nomenclature.
- 08Kh18N10 and 03Kh18N11, the equivalents for 403 and 403L in GOST nomenclature.
