Hastelloy C22 Disc / seat ring / square bar / round bar customize
Hastelloy C22 is a nickel-chromium-molybdenum alloy. It has high
resistance corrosion and metallurgical stability. It is not
sensitized during heating or welding.
Hastelloy C-22 is a omnipotent of nickel, chromium and molybdenum
mixed alloy, with better corrosion resistance performance than
other alloys, for example, Hastelloy C-276 alloy, C-4 alloy and 625
alloy. Hastelloy C-22 have a good resistance performance to
pitting, crevice corrosion and stress corrosion cracking, have
excellent inoxidability water medium performance, including the
wet-chlorine, nitric acid or oxidizing acid mixed acid with
chloride ion. Meantime, Hastelloy C-22 possesses perfect resistance
to reduction and oxidation of processing enviroments, then it can
be used in some complicated environment or with many different
manufacture target factory depend on the omnipotent performance.
Hastelloy C-22 possess prominent resistance performance to
different chemical environments, including strong oxidizing matter,
such as iron chloride, copper chloride, chlorine, heat pollution
liquid(organic and inorganic), formic acid, acetic acid, acetyl
oxide, sea water and salting liquid and so on. Hastelloy C-22 alloy
can resist the grain boundary precipitate form when jointing heat
affected zone, this performance made it can applied in many kinds
of chemical processing.
Hastelloy C-22 Metallurgical structure
Hastelloy C-22 is face-centered cubic lattice structure.
Hastelloy C-22 Corrosion resistance
Hastelloy C-22 alloy suit for many kinds of chemical process
industry which contain the oxidizing medium and reductant. High
molybdenum and chromium content make it can resist the chloride
corrosion, and tungsten makethis corrosion
resistancebetter.Hastelloy C-22 is one of a few material that can
resist thecorrosion of moist chlorine, hypochlorite and chlorine
dioxide, this alloy have prominent corrosion resistanceto high
concentration chlorate( iron chloride and copper chloride).
Hastelloy C-22 Application field:
Hastelloy C-22 is widely used in the chemical field and
petrifaction field, such as the element of chloride organic and
catalyze system.This material especially suit for high temperature
environments, impure inorganic acid and organic acid (such as
formic acid and acetic acid), sea-water corrosion environments.
