Heat Treatment Wrought Nickel & Cobalt Alloy Parts

AMS 2774 is an aerospace material specification that governs the heat treatment of wrought nickel alloys and cobalt alloys. It defines the required thermal cycles, furnace temperature uniformity requirements, quench methods, and testing requirements — including hardness and mechanical property verification — to ensure treated parts meet the performance standards required by aerospace and defense applications.

The two primary heat treatment types for nickel and cobalt alloys are annealing (including solution annealing) and age hardening (precipitation hardening). Annealing restores ductility and relieves stress by heating and controlled cooling, while age hardening strengthens the alloy by precipitating secondary phases within the microstructure after solution treatment and quenching.

Yes. Wrought nickel and nickel-based alloys respond very well to heat treatment. Processes such as normalizing, solution annealing, and stress relief are routinely applied to nickel alloys to optimize grain structure, tensile strength, ductility, and corrosion resistance. At MTS Forge, we perform these cycles in-house under documented, traceable procedures compliant with AMS 2774 and applicable military standards.

MTS Forge heat treats a broad range of wrought nickel and cobalt alloys used in aerospace, defense, power generation, and commercial nuclear applications, including Monel K-500 and other high-performance alloys. We apply normalizing and other heat treatment cycles across our full forged product range, from closed die forgings to upset forgings and custom shapes.

MTS Forge performs normalizing heat treatment entirely in-house at our Coatesville, PA facility. Normalizing involves heating forged components above their upper critical temperature and then air-cooling to produce a refined, uniform grain structure. This eliminates the need to outsource thermal processing, reducing lead times, minimizing handling risk, and maintaining unbroken traceability throughout the production sequence.

The forging process creates uneven grain growth and internal stresses across a component due to the high temperatures and deformation involved. Normalizing breaks up these irregular grain structures and relieves residual stress, producing a uniform microstructure throughout the part. The result is improved tensile strength, enhanced toughness and ductility, and better machinability — critical requirements in aerospace, defense, and nuclear applications.

MTS Forge's heat treatment operations are governed by our comprehensive Quality Assurance Program, which includes certifications to Mil I 45208, NCA 3800, and Mil Q9858. All heat treatment cycles for wrought nickel and cobalt alloy parts are performed to AMS 2774 requirements. Complete material and process traceability is maintained from incoming raw material through final inspection and delivery.

MTS Forge serves aerospace, defense, commercial nuclear, power generation, chemical processing, and machine manufacturing industries with heat treatment of nickel and cobalt alloy forged components. Our facility in Coatesville, PA is positioned to support manufacturers and procurement teams across Pennsylvania and throughout the United States requiring AMS 2774-compliant thermal processing and fully documented quality records.
