Alloy 625 is a Nickel-Chromium alloy used for its
high strength, excellent fabricability and outstanding
corrosion resistance. Service temperatures range
from cryogenic to 1800 deg.F. Alloy 625 strength
is derived from the stiffening effect of molybdenium
and columbium on its Nickel-Chromium matrix; thus
precipitation-hardening treatments are not required.
This combination of elements also is responsible
for superior resistance to a wide range of corrosive
environments of unusual severity as well as to high-temperature
effects such as oxidation and carburization.
Outstanding resistance to pitting, crevice corrosion,
impingement corrosion and intergranular attack.
Almost complete freedom from Chloride induced stress
Good resistance to mineral acids, such as nitric,
phosphoric, sulphuric and hydrochloric acids.
Good resistance to alkalis and organic acids.
Good mechanical properties.
Used for structures in contact with seawater and
Subject to high mechanical stresses
Flue gas scrubbers components
Superphosphoric acid production equipment
Sour gas production tubes
Offshore industry, marine equipment
High tensile, creep, rupture strength, outstanding
fatigue and thermal-fatigue strength; oxidation
resistance; and excellent weldability and brazeability
make it a good choice in the aerospace industry
