Stainless steel Stainless steel In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable" (inoxidizable), is a steel alloy with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass. Stainless steels are most notable for their corrosion resistance, which increases with increasing chromium content. Additions of molybdenum increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure. Stainless steel's resistance to corrosion and staining, low maintenance,
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
