Inconel®
nickel-chromium-iron alloy **0(UNS N****0 DIN 2.***6)is a standard engineering material
for applications which require resistance to corrosion and heat.
The alloy also has excellent mechanical properties and presents the
desirable combination of high strength and good
workability. The high nickel content gives the
alloy resistance to corrosion by many organic and inorganic
compounds and also makes it virtually immune to chloride-ion
stress-corrosion cracking. Chromium confers resistance to sulfur
compounds and also provides resistance to oxidizing conditions at
high temperatures or in corrosive solutions. The alloy is not
precipitation hard enable; it is hardened and strengthened only by
cold work.
The
material properties and application places The alloy is used extensively in
the chemical industry for its strength and corrosion
resistance. Applications include heaters, stills, bubble
towers, and condensers for processing of fatting acids; evaporator
tubes, tube sheets, and flaking trays for the manufacture of sodium
sulfide; and equipment for handling abietic acid in the manufacture
of paper pulp. The alloy's strength and oxidation
resistance at high temperatures make it useful for many
applications in the heat treating industry. It is used for retorts,
muffles, roller hearths, and other furnace components and for heat
treating baskets and trays.
