Hot Forging Manufacturers for Aerospace and Defense Components

Hot forging is used to create strong metal components for applications that require reliable mechanical performance, including aerospace, defense, power generation, heavy equipment, oil and gas, motorsports, bearings, and gears. Heating metal before deformation allows it to be formed more effectively and can improve grain flow. It is especially valuable when strength, fatigue resistance, and material integrity are important.

Hot forging shapes metal above its recrystallization temperature, which lowers forming forces and allows substantial deformation of larger or more complex sections. Cold forging is performed at or near room temperature and can provide excellent dimensional consistency and surface finish, but it requires higher forces and is less suitable for some large or difficult-to-form alloys. The right method depends on alloy, geometry, tolerances, and performance requirements.

Open-die forging forms heated metal between dies that do not fully enclose the workpiece. The operator manipulates the billet or bar through repeated pressing to achieve the required shape and size. This method is well suited to large parts, custom dimensions, and lower-volume requirements. It can also support material properties needed for critical components by developing favorable grain flow.

Many carbon steels, alloy steels, stainless steels, nickel alloys, titanium alloys, and other engineered metals can be hot forged when the proper temperature range and processing controls are used. Material selection should account for strength, corrosion resistance, operating temperature, machinability, and applicable specifications. Aero-Vac can help buyers source high-cleanliness melt stock and coordinate the required material condition for their application.

Yes. Forged material is often machined after forging to achieve final dimensions, interfaces, holes, threads, and surface requirements. Near-net-shape machining can reduce excess material removal and simplify downstream production. Aero-Vac provides in-house machining for semi-finished and near-net-shape parts, helping customers coordinate forging and machining through fewer suppliers while maintaining alignment with drawing and material requirements.

Heat treatment may be needed after hot forging to achieve the metallurgical condition specified for the part, such as a required hardness, strength, ductility, or stress-relieved state. The exact process depends on the alloy and applicable specification. Aero-Vac offers thermal processing support and can also work with outside NADCAP heat treaters when production volume or turnaround requirements call for additional capacity.

Testing can confirm that forged material meets specified material and quality requirements before shipment. Depending on the program, this may include destructive methods, such as mechanical or chemical testing, and non-destructive methods that evaluate material without damaging it. Aero-Vac provides independent third-party testing support to confirm conformance and help customers receive documentation appropriate to their stated specifications.

Yes. Aero-Vac supports custom cuts, odd sizes, small quantities, and larger order requirements. Buyers can provide alloy, dimensions, condition, quantity, testing, machining, heat-treatment, and delivery needs so the team can develop custom pricing. This flexibility is useful for prototypes, replacement parts, specialized production runs, and just-in-time programs that do not require a standard mill quantity.
