Stainless steels which – beside the necessary percentage of Chromium – contain a good amount of Nickel and possibly of Molybdenum.

Possible uses of this steel class are: saucepans, hobs, doors and windows, architectural finishes, abattoirs, tanks, cans for drinks and food products; liquefied gas tanks, heat exchangers, control equipment for pollution and smoke extraction, industrial autoclaves.
Its resistance to most chemical aggression makes it most appreciated in the chemical industry. The same type of steel was used in 1929 to build the spire of the Chrysler Building in New York.
