STAINLESS STEEL
ASTM F899 420A | EN 1.4021
Description
ASTM F899 420A is a martensitic stainless chromium steel that is corrosion resistant to water and steam. This requires the hardened and low tempered state and a shiny, polished surface preference. In the high-tempered or annealed condition, the corrosion resistance is reduced.
Due to its chromium content, the alloy shows good corrosion resistance in moderately aggressive, nonchlorine-containing media, such as soaps, solvents and organic acids. This steel is also scaling resistant to oxidizing atmosphere at temperatures up to 600° C.
