As a national supplier of forged
products, Philadelphia Forgings commits to providing customers with
the highest quality forgings. Our customer base extends from regional
areas including Pennsylvania, Delaware, and New Jersey to locations
across the United States. One of the materials that makes filling
this commitment possible is nickel alloy. Forgings in nickel alloy
demonstrate controlled thermal expansion properties as well as resistance
to corrosion and heat deformation.
Properties of Nickel Alloy Forgings
Most of the nickel alloys used for commercial
forged products are selected for resistance to both heat and corrosion.
The higher chromium content helps nickel alloy forgings retain their
shapes during prolonged exposure to heat and also avoid damage by
oxidation. Nickel alloy forgings that are to be used in fresh or
sea water applications are chosen based on the ability of a particular
grade of nickel alloy to resist corrosion. Nickel also affects the
thermal expansion properties of a metal, either by expansion predictability
or low thermal expansion control.
Philadelphia Forgings supplies forged products in the following types
of nickel alloy:
Inconel® 600 was one of the first nickel alloys; this type of nickel
alloy forging combines nickel, chromium, and iron into a high strength
Inconel® 601 is a high-temperature metal. Alloy 601 forgings include
both aluminum and silicone for improved resistance to oxidation.
Inconel® 625 combines aluminum and titanium. This type of metal forging
can be age hardened for increased strength and wear resistance.
Inconel® 725 is precipitation hardened and mixes niobium with titanium
and molybdenum. Products forged from this material resist creep
as well as stress rupture.
Inconel® X-750 includes a higher amount of chromium; its forgings
can be age hardened to achieve maximum levels of strength.
Inconel® 800 is a basic nickel alloy that can be forged to make products
that resist carburization and oxidation at elevated temperatures.
Inconel® 800 HT is similar to Inconel® 800 but also contains
aluminum and titanium. Products forged from this material have optimum
heat resistance properties.
Inconel® 825 contains titanium as a stabilizing component and molybdenum
for pitting resistance. Its forgings are often used for marine applications.
Inconel® 903 offers a low thermal expansion coefficient. Alloy 903
metal forgings exhibit high levels of strength.
Hastelloy® C contains chromium and can be forged into products that
demonstrate excellent corrosion resistance.
Hastelloy® C-22 can create forged products
that exhibit excellent corrosion resistance in severe environments
as well as in the presence of chlorine and acid chlorides.
Hastelloy® C-276s forgings provide excellent resistance to corrosion
by seawater as well as pitting and crevice corrosion.
Hastelloy® X is a high temperature alloy that contains chromium and
molybdenum. Its forgings provide resistance to damage by corrosion
and prolonged exposure to heat.
is an age-hardenable superalloy. Waspaloy® forgings
provide strength at high temperatures and resist corrosion as well
Monel® 400. Resistant to a variety of corrosive media, including salt water
and concentrated acids, Monel® 400 forgings exhibit
good ductility and tensile strength.
Monel® 500. Containing aluminum and titanium for increased strength and toughness, Monel® K 500
forgings are age hardenable, and able to provide high fatigue and
