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 product.

• 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-276’s 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.

• Waspaloy^® is an age-hardenable superalloy. Waspaloy^® forgings provide strength at high temperatures and resist corrosion as well as oxidation.
