SAE 304 stainless steel SAE 304 stainless steel SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18–20%) and nickel (between 8–10.5%) metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel and is essentially non-magnetic. 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. The composition was developed by W. H. Hatfield at Firth-Vickers in 1924 and was marketed under the trade name “Staybrite 18/8”. It is specified
Stainless steel on the surface. A final finish can then be applied to achieve the desired aesthetic appearance. Most of the world stainless steel production is produced by the following process Hot rolled coils are pickled in acid solutions to remove the oxide scale on the surface, then subsequently cold rolled (Sendzimir rolling mills), annealed in a protective atmosphere, until the desired thickness and surface finish is obtained. Further operations such as slitting, tube forming, etc. can be carried out in downstream facilities. Hot rolled bars are straightened, then machined to the required tolerance and finish. Wire rod coils are subsequently processed
