Nickel Alloy Forged Parts

All Metals & Forge Group manufactures high-performance nickel alloy forged parts for extreme temperature, corrosion, and high-wear applications. These materials, often referred to as superalloys, deliver exceptional strength and resistance in aerospace, marine, chemical processing, oil and gas, and power generation industries.

Nickel alloys, cobalt alloys, and superalloys form the foundation of many mission-critical components. Because these alloys maintain mechanical integrity under severe conditions, engineers specify them for environments where carbon or alloy steels cannot perform reliably.

Nickel Alloys, Cobalt Alloys, and Superalloys

Nickel alloy forged parts include well-known material families such as:

• Monel® alloys, developed with copper and aluminum for corrosion resistance

• Inconel® alloys, strengthened with chromium and iron for high-temperature performance

• Hastelloy® alloys, enhanced with molybdenum and tungsten for aggressive chemical resistance

Common alloy grades include 600, 625, 718, 725, 800, K500, and C276. Most contain significant chromium content for oxidation resistance. Additionally, manufacturers add elements such as titanium, aluminum, cobalt, vanadium, and columbium to improve precipitation hardening and elevated temperature strength.

Because of these metallurgical enhancements, superalloy forged parts withstand harsh chemical media, saltwater exposure, sulfur-bearing gases, and extreme thermal cycling.

Performance in Extreme Environments

Nickel alloy forged parts serve applications involving:

• Aircraft engines and aerospace systems

• Offshore and subsea oil and gas components

• Chemical and petrochemical processing

• Marine and saltwater environments

• Military and defense equipment

For example, Hastelloy B, containing approximately 65% nickel and 30% molybdenum, resists hydrochloric acid at high concentrations and temperatures. Similarly, Inconel grades perform reliably in high-heat turbine and exhaust systems.

Because these alloys resist scaling, oxidation, and stress corrosion cracking, they provide long service life in environments that rapidly degrade other materials.

Forging and Heat Treatment of Nickel Alloy Forged Parts

Forging nickel alloys requires strict temperature control. These materials offer high strength at elevated temperatures; however, they can crack if improperly handled during hot working. Therefore, we apply controlled reduction ratios and carefully monitored forging cycles.

Most nickel alloy forged parts benefit from a post-forge anneal followed by air cooling or water quenching, depending on geometry. In many cases, we then apply a precipitation hardening treatment to achieve specified mechanical properties.

Non-destructive testing throughout production confirms internal integrity and material soundness.

Quality Control and Machining Capabilities

All Metals & Forge Group operates under an ISO 9001:2015 and AS9100D registered quality system. We begin each project by evaluating end use, required mechanical properties, geometry, and delivery schedule.

Every nickel alloy forged part undergoes ultrasonic testing to verify internal quality. In addition, we rough machine forgings to within 3 mm of finished dimensions. This practice reduces CNC machining costs and improves dimensional efficiency. Our standard rough-machined finish is 250 RMS to ensure accurate inspection.

When required, we perform finish machining to tolerances as tight as ±0.001 inch with 64 or 32 RMS surface finishes. Many suppliers ship superalloy components as-forged or at 500 RMS; however, our machining standards significantly reduce downstream processing.

From inquiry through final shipment, we actively manage quality at every stage. Whether producing a single component or a full production run, we deliver nickel alloy forged parts engineered for extreme service conditions.
