Nickel Alloy Round Bar Inconel 625 Round Bar ASTM B564 UNS N06625 Forging Bar
INCONEL nickel-chromium alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength,excellent fabricability (including joining), and outstanding corrosion resistance. Service temperaturesrange from cryogenic to 1800°F (982°C). Composition is shown as below.
Strength of INCONEL alloy 625 is derived from the stiffening effect
of molybdenum and niobium on its nickel-chromium matrix; thus
precipitationhardening 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.
The properties of INCONEL alloy 625 that make it an excellent
choice for sea-water applications are freedom from local attack
(pitting and crevice corrosion), high corrosion-fatigue strength,
high tensile strength, and resistance to chloride-ion
stress-corrosion cracking. It is used as wire rope for mooring
cables,propeller blades for motor patrol gunboats, submarine
auxiliary propulsion motors, submarine quickdisconnect fittings,
exhaust ducts for Navy utility boats,sheathing for undersea
communication cables, submarine transducer controls, and steam-line
bellows. Potential applications are springs, seals, bellows for
submerged controls, electrical cable connectors, fasteners,flexure
devices, and oceanographic instrument components.
High tensile, creep, and rupture strength; outstanding fatigue and
thermal-fatigue strength; oxidation resistance; and excellent
weldability and brazeability are the properties of INCONEL alloy
625 that make it interesting to the aerospace field. It is being
used in such applications as aircraft ducting systems, engine
exhaust systems, thrust-reverser systems, resistancewelded
honeycomb structures for housing engine controls, fuel and
hydraulic line tubing, spray bars, bellows, turbine shroud rings,
and heat-exchanger tubing in environmental control systems. It is
also suitable for combustion system transition liners, turbine
seals, compressor vanes, and thrust-chamber tubing for rocket.
The outstanding and versatile corrosion resistance of INCONEL alloy
625 under a wide range of temperatures and pressures is a primary
reason for its wide acceptance in the chemical processing field.
Because of its ease of fabrication, it is made into a variety of
components for plant equipment. Its high strength enables it to be
used, for example, in thinner-walled vessels or tubing than
possible with other materials, thus improving heat transfer and
saving weight. Some applications requiring the combination of
strength and corrosion resistance offered by INCONEL alloy 625 are
bubble caps, tubing, reaction vessels, distillation columns, heat
exchangers, transfer piping, and valves.
In the nuclear field, INCONEL alloy 625 may be used for
reactor-core and control-rod components in nuclear water reactors.
The material can be selected because of its high strength,
excellent uniform corrosion resistance, resistance to stress
cracking and excellent pitting resistance in 500°-600°F (260-316°C)
water. Alloy 625 is also being considered in advanced reactor
concepts because of its high allowable design strength at elevated
temperatures, especially between 1200°-1400°F (649-760°C).
