SAE steel grades. 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.
AISI 420 High-Carbon steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, AISI 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened.
Aplicaciones: 1.4021 | AISI 420 es un acero al cromo, martensítico, resistente a los ácidos con una buena resistencia a la corrosión y en medios de cloruro moderadamente corrosivos, tales como ácidos orgánicos, jabones y disolventes. Las aplicaciones principales son en la industria de la ingeniería, petróleo y petroquímica mecánica y
Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …
AISI Type 420 provides full corrosion resistance only in the hardened or hardened and stress relieved conditions. In these conditions, its corrosion resistance is similar to Type 410. Type 420 resists corrosion by the atmosphere, fresh water, mine water, steam, carbonic acid, crude oil, gasoline, perspiration, alcohol, ammonia, mercury, sterilizing solutions, …
