Nickel based High-temperature Alloy Forgings

Nickel Based High-Temperature Alloy Forgings

Superalloy forgings manufactured to your specification, certified to the heat.

IInconel 718 ring forging with a machined bolt-hole circle around the circumference.
Inconel 718 ring forging. Composition and mechanical properties are certified to the grade stated on the order.

Nickel-based superalloy forgings are supplied for service where a component must hold its strength and its shape while working at elevated temperature — under load, under thermal cycling, and often in an environment that attacks the surface as well.

Typical products and materials: superalloy materials for gas turbines, Inconel 718 forgings.

Why Forged, Not Cast

For a component that works hot, the manufacturing route is a material decision rather than a cost decision.

  • Grain flow follows the part. Forging works the metal so the grain structure runs along the shape of the component rather than randomly, which is what gives a ring or a disc its strength in the direction it is loaded.
  • Soundness is inherent to the process. High-temperature service is unforgiving of internal discontinuities; a forging does not carry the solidification-related defects that a casting can.
  • The section can be worked, not just filled. Mechanical working refines the structure in a way that heat treatment alone cannot.

Where a geometry is too complex to forge to shape, it is commonly forged to a near-net preform and finished by machining.

Inconel 718 Support Ring — Chemical Composition

Inconel 718 is a precipitation-hardening nickel-chromium alloy. Niobium is the principal hardening element, with molybdenum contributing solid-solution strengthening, and titanium and aluminium forming the strengthening precipitates. Chromium provides oxidation and corrosion resistance.

Element Requirement (% by weight)
Carbon (C) 0.012 – 0.036
Manganese (Mn) ≤ 0.35
Silicon (Si) ≤ 0.35
Phosphorus (P) ≤ 0.015
Sulfur (S) ≤ 0.0010
Chromium (Cr) 17.00 – 19.00
Nickel (Ni) 52.00 – 55.00
Molybdenum (Mo) 2.80 – 3.15
Niobium (Nb) 5.20 – 5.55
Tantalum (Ta) ≤ 0.10
Titanium (Ti) 0.75 – 1.15
Aluminium (Al) 0.35 – 0.65
Cobalt (Co) ≤ 1.00
Copper (Cu) ≤ 0.30
Boron (B) ≤ 0.006
Iron (Fe) 16.00 – 19.00

Values are those of the applicable procurement specification, which is tighter than the general ASME SB 637 range in several elements. Composition is certified per heat against this specification.

Mechanical Properties of Inconel 718 Support Ring (ASME SB 637)

ASME SB 637 covers nickel-chromium-niobium-molybdenum alloy (UNS N07718) in the form of bar, forgings and forging stock. Mechanical properties under this specification depend on the heat-treatment condition, so the condition is part of the specification — not a manufacturing preference to be settled later.

(HB)
Ambient (room temperature) ≥ 1035 ≥ 1240 ≥ 12 ≥ 12 ≥ 331
650 °C ≥ 860 ≥ 965 ≥ 12 ≥ 12 Not specified

Values are minimums as stated. Hardness is not specified at 650 °C.

Grade Equivalents

Inconel 718 is referenced under several numbering systems. They are commonly treated as interchangeable, but the composition ranges and acceptance criteria are not identical across every system, so an equivalent should be confirmed rather than assumed.

Designation system Inconel 718 Inconel 625
UNS N07718 N06625
EN numeric 2.4668 2.4856
Composition designation NiCr19NbMo NiCr22Mo9Nb

Equivalents are commonly cited; composition ranges and acceptance criteria are not identical across every system.

Where a drawing specifies an equivalent grade, the basis of the equivalence is confirmed in writing before production — whether the match is on composition, mechanical properties, heat-treatment condition, or service performance.

Machining & Handling

Inconel 718 work-hardens during cutting. Cutting parameters, tool condition and the condition of the material being machined all affect the result, and machining is therefore planned rather than improvised: which condition the part is machined in — solution-treated or aged — is decided from the specification and the required final properties.

Documentation Available

  • Mill certificate to the applicable specification, traceable to heat number
  • Heat-treatment records retained against the part
  • Non-destructive examination where the specification requires it
  • Dimensional inspection report issued per shipment

See also: NDT (Non Destructive Testing) service

Enquiry Checklist

  • Drawing or 3D model, and the specification it is made to
  • Grade and heat-treatment condition required
  • Quantity
  • Examination and certification requirements
  • Where no drawing exists yet — a new design, or an existing part without usable documentation — the duty the part has to perform: temperature range, load case, cycling frequency, and the environment it works in. Where you are replacing an existing part, how it wears in service is useful additional input

Heavy Planetary Carrier and Transmission Components — Large Format Precision Machined to Drawing

Heavy Planetary Carrier and Large Format Transmission Components — Precision Machined to Customer Drawing

SMI manufactures heavy planetary carriers and large format transmission components to customer drawing and technical specification — covering planet carriers, ring gears, output flanges and gear shaft assemblies at weights and dimensions beyond the envelope of standard industrial reducer supply. The planet carrier shown below — Φ680 × 620mm, 810KG — is representative of the scale and precision machining capability SMI applies to heavy transmission component supply.

Every component in this category is produced to the customer’s own engineering drawing. Material grade, dimensional tolerances, heat treatment specification, surface finish and inspection requirements are all defined by the customer’s design — SMI’s role is to manufacture to that specification with the casting, forging and precision machining capability required to achieve it consistently.

SMI heavy planet carrier precision machined cast steel Phi 680 x 620mm 810KG to customer drawing specification for energy drilling mining and heavy industrial transmission systems
SMI heavy planet carrier — Φ680 × 620mm, 810KG, precision machined cast steel to customer drawing and specification

Representative Component — Planet Carrier Φ680 × 620mm, 810KG

The planet carrier is the most structurally demanding component in a planetary transmission system. It carries the full output torque of the reducer, supports the planet gear bearing loads on all pin positions simultaneously, and must maintain precise dimensional relationships between pin bores across its full service life under cyclic loading.

At Φ680 × 620mm and 810KG, the component shown represents a transmission system capable of handling several thousand kilowatts of input power — consistent with the drive system requirements of energy drilling equipment, large ball mills, tunnel boring machine cutter head drives and heavy marine lifting machinery. Key manufacturing requirements for a component at this scale include:

  • Casting integrity — at 810KG, internal soundness of the casting is critical. Any porosity or inclusion concentration at the hub or pin boss locations will initiate fatigue cracking under the cyclic torque loads of heavy drive service. SMI’s casting practice for heavy components includes controlled pouring, riser design and post-casting inspection to verify internal quality before machining begins
  • Pin bore positional accuracy — the angular and radial position of each planet pin bore determines the load sharing between planet gears. Positional error concentrates load on individual planets and reduces the effective torque capacity of the assembly. SMI machines pin bores to the positional tolerances specified in the customer’s drawing, verified by CMM inspection
  • Hub bore concentricity — the central hub bore carries the output shaft or sun gear shaft bearing. Concentricity relative to the pin bore pitch circle is machined and verified to drawing tolerance
  • Flange face flatness and bolt circle accuracy — the output flange face and bolt circle are machined to the assembly tolerances required for correct mating with the adjacent shaft or housing component

Heavy Transmission Component Range

Planet Carriers

Cast steel planet carriers from small industrial sizes up to 810KG and above — machined to customer drawing for single-stage and multi-stage planetary systems. Hub bore, pin bore positions, flange face and bolt circle all machined to drawing tolerance. CMM dimensional verification as standard on large format components.

Internal Ring Gears

Large format internal ring gears — cast or forged blanks, internal gear cut to specified module, tooth profile accuracy grade and face width. Heat treatment to specified surface hardness. Ring gear housing bore and mounting features machined to assembly drawing. Available in through-hardened and case-hardened configurations to customer specification.

Output Flanges and Carrier Flanges

Heavy output flanges and carrier flanges — precision machined bolt circle, mating face flatness and bore dimensions to assembly drawing tolerances. Flange face machining to the surface finish specified for the sealing or mating interface requirements of the customer’s application.

Planet Gear Shaft Assemblies

Planet gear shaft assemblies — external gear cutting to specified module and accuracy grade, shaft journal machining to bearing fit dimensions, spline features to customer profile specification. Heat treatment and surface finish to drawing. Available as individual components or as matched sets for a complete planet gear stage.

Sun Gears and Input Shaft Assemblies

Sun gear and input shaft assemblies — external gear cutting, journal machining and spline or coupling features to customer drawing. Case hardening or nitriding to specified surface hardness and case depth. Balanced to customer requirement for high-speed input shaft applications.


Application Sectors

Energy and Drilling Equipment

Heavy planetary transmission components for the drive systems of energy drilling and production equipment — including drawworks transmission systems, mud pump drives and rotary table drives for oil and gas drilling applications. These applications demand high torque density, resistance to shock loading and consistent dimensional accuracy across the full component set to ensure reliable operation under the demanding conditions of drilling service.

Mining and Mineral Processing

Large format planet carriers, ring gears and output flanges for ball mill drives, SAG mill drives, crusher drives and mine hoist transmission systems. Mill drive planetary systems operate continuously under high torque and are subject to the cyclic shock loads generated by the grinding charge — requiring casting integrity and dimensional accuracy that SMI’s heavy component manufacturing capability is designed to deliver.

Tunnelling and Construction Machinery

Heavy planetary transmission components for cutter head drive systems and large crawler crane travel drives. Cutter head planetary systems operate under extreme and variable load conditions — requiring robust casting design, controlled heat treatment and precise pin bore geometry to maintain load sharing across all planet positions throughout the service life of the drive.

Marine and Offshore Lifting

Planet carriers and ring gears for ship deck machinery, heavy lift crane slewing and hoisting drives, and offshore winch transmission systems. Marine applications require material certification to classification society standards — available on request from SMI.
