Nickel and Cobalt Forged Parts

Nickel has been designed to perform as forgings in a variety of shapes and sizes, as well as seamless rolled rings for environments where the metal must withstand high temperatures, highly corrosive conditions such as salts or acids, and wear resistance.  Many of these are trademarked metals, such as Inconel®, Incoloy®, Hastelloy®, and Monel®.  Their chemistry and resultant mechanical properties are defined by their designations, such as 600, 625, 716, 718, 725, K500, or C276.  There are also nickel-copper alloys, nickel-iron alloys, nickel-chromium alloys, nickel-titanium alloys, and nickel-molybdenum alloys.  Each of these has unique characteristics for specific end uses.

Like nickel alloys, materials that require high resistance to heat or corrosive environments include cobalt in their chemistry.  This improves their resistance to heat, such as valves in internal combustion engines, and gas turbine engines.  Nickel and cobalt alloys are also referred to as superalloys or high-performance alloys because they offer better creep, oxidation, and corrosion resistance will retaining their mechanical properties, even at high temperatures.

Nickel and cobalt alloys open die forgings and seamless rolled rings are widely used in the energy-producing industries, including nuclear, tidal, wind, hydroelectric, and oil and gas.  They are also used in gas turbines for high-temperature, high-temperature performance, such as aircraft and aerospace.  The characteristics of nickel alloys include corrosion resistance, high strength, heat resistance, ductility, soft magnetic properties, weldability, thermal conductivity, electrical conductivity, and low thermal expansion coefficients.

The chemical and mechanical properties of nickel and cobalt alloys make them an excellent choice for component parts finish machined from round, flat, square and hex bars, blocks and rectangles, discs and rings, cylinders, or shapes with steps, flanges, or complex finish machining requirements.
