Nickel Alloy

Incoloy 800

A nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres. It also resists corrosion by many aqueous environments. The alloy maintains a stable, austenitic structure during prolonged exposure to high temperatures. Used for process piping, heat exchangers, carburizing equipment, heating-element sheathing, and nuclear steam-generator tubing. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Incoloy 800HT

A nickel-iron-chromium alloy having the same basic composition as INCOLOY alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum, and titanium contents in conjunction with a high-temperature anneal. Used in chemical and petrochemical processing, in power plants for super-heater and re-heater tubing, in industrial furnaces, and for heat-treating equipment. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Incoloy 825

A nickel-iron-chromium alloy with additions of molybdenum and copper. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. The alloy is especially resistant to sulfuric and phosphoric acids. Used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Incoloy 925

A precipitation-hardenable nickel-iron-chromium alloy with additions of molybdenum and copper. It combines the high strength of a precipitation-hardenable alloy with the excellent corrosion resistance of INCOLOY alloy 825. The alloy has outstanding resistance to general corrosion, pitting, crevice corrosion, and stress-corrosion cracking in many aqueous environments including those containing sulfides and chlorides. Used for surface and down-hole hardware in sour gas wells and for oil-production equipment. Standard product forms are round, flats, forging stock, pipe, tube, and wire.

Inconel 600

A nickel-chromium alloy with good oxidation resistance at high temperatures and resistance to chloride-ion stress-corrosion cracking, corrosion by high-purity water, and caustic corrosion. Used for furnace components, in chemical and food processing, in nuclear engineering, and for sparking electrodes. Standard product forms are round, hexagon, extruded section, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Inconel 601

A nickel-chromium alloy with an addition of aluminum for outstanding resistance to oxidation and other forms of high-temperature corrosion. It also has high mechanical properties at elevated temperatures. Used for industrial furnaces; heat-treating equipment such as baskets, muffles, and retorts; petrochemical and other process equipment; and gas-turbine components. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Inconel 625

A nickel-chromium alloy with an addition of aluminum for outstanding resistance to oxidation and other forms of high-temperature corrosion. It also has high mechanical properties at elevated temperatures. Used for industrial furnaces; heat-treating equipment such as baskets, muffles, and retorts; petrochemical and other process equipment; and gas-turbine components. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.

Inconel 718

The material of choice for the majority of aircraft engine components with service temperatures below 1200°F (650°C). Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing also significant amounts of iron, niobium, and molybdenum along with lesser amounts of aluminum and titanium. It combines corrosion resistance and high strength with outstanding weldability including resistance to postweld cracking. The alloy has excellent creep-rupture strength at temperatures to 1300°F (700°C).

Inconel 725

An age harden-able nickel based alloy containing chromium, iron and molybdenum, additional of smaller percentage of niobium and titanium.

Monel 400

A nickel-copper alloy with high strength and excellent corrosion resistance to sea water, acidic, alkaline media and other environments.

Monel K500

A precipitation-harden-able nickel-copper alloy that combines the corrosion resistance of Alloy 400 with greater strength and hardness.

Nickel 200

Commercially pure (99.6%) wrought nickel with good mechanical properties and resistance to a range of corrosive media. Good thermal, electrical, and magnetostrictive properties. Ferromagnetic. Used for a variety of processing equipment, particularly to maintain product purity in handling foods, synthetic fibers, and alkalis. Standard product forms are round, flats, pipe, tube, plate, sheet, forging stock, strip, and wire.

Nickel 201

Commercially pure (99.6%) wrought nickel essentially the same as Nickel 200 but with a lower carbon content to prevent embrittlement by intergranular carbon at temperatures over 600°F (315°C). Lower carbon content also reduces hardness, making Nickel 201 particularly suitable for cold-formed items. Ferromagnetic. Standard product forms are round, flats, pipe, tube, plate, sheet, forging stock, strip, and wire.

Nilo 42

A nickel-iron controlled-expansion alloy containing 42% nickel. It has a low and nominally constant coefficient of thermal expansion from room temperature to about 570°F (300°C). Used for semiconductor lead frames in integrated circuits, bi-metal thermostat strip, thermostat rods, for ceramic-to-metal seals with alumina ceramics, and various glass-to-metal seals such as the core of copper-clad wire for sealing into glass envelopes of electric bulbs, radio valves, television tubes, and fluorescent lights. Standard product forms are tube, sheet, strip, and wire.

Nimonic 75

A nickel-chromium alloy with good mechanical properties and oxidation resistance at high temperatures. Used for sheet-metal fabrications in gas-turbine engines, for components of industrial furnaces, for heat-treating equipment and fixtures, and in nuclear engineering. Standard product forms are round, hexagon, flats, extruded section, tube, pipe, plate, sheet, strip, and wire.

Nimonic 80A

A nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium. The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500°F (815°C).

Standard product forms are round, hexagon, flats, extruded section, tube, plate, sheet, and wire.

Nimonic 90

A precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). The alloy also has good resistance to high-temperature corrosion and oxidation. Used for blades and discs in gas turbines, hot-working tools, and springs. Standard product forms are round, flats, extruded section, plate, sheet, strip, tube, and wire.

Hastelloy C276

Versatile corrosion-resistant alloy, usually does not need to be solution heat treated after welding and has vastly improved fabricability, excellent resistance to localized corrosion and to both oxidizing and reducing media. Resists formation of grain-boundary precipitates and is therefore suitable for chemical process applications in the as-welded condition. C-276 has excellent resistance to strong oxidizers like ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, seawater, brine solutions, sulfur compounds, wet chlorine gas, hypochlorite and chlorine dioxide.

Hastelloy C22

A most versatile nickel-chromium molybdenum-tungsten alloy available today with improved resistance to both uniform and localized corrosion as well as to a variety of mixed industrial chemicals. The C22 alloy exhibits superior weldability.  

Hastelloy X

Solid-solution-strengthened with very good high-temperature strength and very good resistance to oxidizing environments up to about 1095°C, and good carburization resistance. Applications include materials for fabricated or forged parts in gas turbine engines, and chemical and petrochemical plants, power plant and industrial heating applications.
