Characteristic
1. Excellent corrosion resistance of different kinds of media in
both oxidation and reduction environments.
2. Excellent resistance of pitting and crevice corrosion, and won't
happen stress corrosion cracking because of chloride.
3. Excellent resistance of the inorganic acid corrosion
performance, such as nitric acid, phosphoric acid, sulfuric acid,
hydrochloric acid and the mixture of sulfuric acid and hydrochloric
acid.
4. Excellent corrosion resistance of different kinds of inorganic
acid mixture performance.
5. Good corrosion resistance of a variety of concentrations of
hydrochloric acid when the temperature up to 40° C.
6. Good machining and welding, no weld cracking sensitivity.
7. Have pressure vessel authentication for the wall temperature
between -196 ~ 450° C.
8. Apply for the highest standard lever VII of acidic environment
by the NACE ( MR-01-75) authorized.
Inconel 625 Metallurgical structure
Inconel 625 is face-centered cubic lattice structure. Dissolve out
the carbon granule and instability quaternary phase, then change it
to stability Ni3 (Nb, Ti) trimetric lattice around 650° C after a
long time heat preservation. Nickel-chromium content will strength
the mechanical performance in the state solution while suppress the
plasticity.
Inconel 625 Corrosion resistance
625 own a very good corrosion resistance in many media, especially
with excellent resistance to pitting, crevice corrosion,
intercrystalline corrosion, and erode in oxide, also good
resistance to inorganic acid corrosion, such as nitric acid,
phosphoric acid, sulfuric acid and hydrochloric acid. 625 can
resist the alkali and organic acid corrosion in the oxidation and
reduction environment. Effect resists the chloride reduction stress
corrosion cracking. Normally no corrosion in the sea-water and
industry environments since high corrosion resistance to the
sea-water and salting liquid, as well as in high temperature,
without sensitivity during welding. 625 have the resistance to
oxidation and carbonizing in the static and cycle environments,
also hacve the resistance the chlorine corrosion.
Inconel 625 Application field
Soften annealing low carbon alloy 625 widely used in the chemical
process industry, good corrosion resistance and high strength made
it an good choice for structural parts. 625 have application in
sea-water for local mechanical stress attach.
