Aerospace Forgings — The Most Demanding Manufacturing Specification in Any Industry

Aerospace forgings — particularly rotating engine components (turbine disks, compressor disks, fan disks) in nickel superalloys and titanium — represent the absolute apex of precision forging technology: a single CFM LEAP-1A engine compressor disk (in Ti-6Al-4V or IN718, 400mm OD, 80kg weight) is subjected to 30,000+ thermal cycles (takeoff-to-cruise-to-landing) over a 30,000-flight-hour engine life, centrifugal stress of 200+ MPa at 16,000 rpm, and temperature ranges of −40°C (takeoff in Arctic) to 650°C (HPT entry for IN718 disk). Any forging defect — a crack, porosity, inclusion, or grain boundary weakness — can lead to an uncontained rotor failure, which is a catastrophic aviation accident. This is why aerospace forging specifications (AMS — Aerospace Material Specifications issued by SAE International, AMS 4928 for Ti-6Al-4V, AMS 5664 for IN718) require: vacuum arc remelted (VAR) or vacuum induction melted + electroslag remelted (VIM+ESR) raw material, AMS 2750F furnace pyrometry (±3°C temperature accuracy in all heat treatment furnaces), NADCAP (National Aerospace and Defense Contractors Accreditation Program) certification for heat treatment and NDE, and full first article inspection (FAI) per AS9102. Shivam Forge's AS9100 Rev D-certified aerospace forging operation serves HAL, DRDO, Bharat Forge, and is pursuing NADCAP qualification for international OEM supply.

Standards and Certifications

AS9100 Rev D — International Aerospace Quality Management System

AS9100 Rev D (based on ISO 9001:2015 + aerospace sector additions: risk management, FOD — Foreign Object Damage prevention, configuration management, first article inspection) is mandatory for all commercial aerospace suppliers. Our AS9100 Rev D certification (TÜV Rheinland) covers aerospace forging manufacture with APQP, PPAP equivalent (FAI per AS9102), and nonconformance management per SAE AS9138.

AMS 2750F — Pyrometry for Aerospace Heat Treatment

AMS 2750F (Pyrometry — Aerospace Material Specification for thermal processing equipment) requires furnace temperature uniformity surveys (TUS) quarterly, system accuracy tests (SAT) monthly, thermocouples calibrated per NIST traceable standards, and Class 2 furnace (±10°F / ±5.5°C temperature uniformity) for titanium solution heat treatment. Our aerospace heat treatment furnaces meet AMS 2750F Class 2 requirements.

NADCAP — National Aerospace Defense Contractors Accreditation

NADCAP (Performance Review Institute) accreditation is required by Boeing, Airbus, GE, Pratt & Whitney, Safran, and Rolls-Royce for heat treatment and NDE of aerospace forgings. NADCAP Heat Treatment (AC7102) and NADCAP NDE (AC7114 for UT, PT, MT) accreditation is under active pursuit for Shivam Forge's aerospace forging operation — current supply to HAL and DRDO under Indian CEMILAC (Centre for Military Airworthiness and Certification) approved vendor framework.

For supply to US defence aerospace programmes (F-35, AH-64E, Black Hawk via Sikorsky India ToT): DFARS 252.225-7009 (specialty metals melted in the US) and DFARS 252.225-7014 (preference for domestic speciality metals) compliance documentation. India is a qualified DFARS-exempt nation for US DoD procurement under the India-US DTTI (Defence Technology and Trade Initiative) — enabling Indian forge shops to supply US DoD programmes without DFARS specialty metal restriction.

Aerospace Forgings — The Most Demanding Manufacturing Specification in Any Industry

Aerospace forgings — particularly rotating gas turbine engine components in nickel superalloys (IN718, Rene 65, Rene 104) and titanium alloys (Ti-6Al-4V, Ti-6246, Ti-17) — represent the absolute technical apex of precision forging manufacture. No other industry specifies more rigorous material, process, and inspection requirements: VAR or VIM+ESR melt for maximum cleanliness (oxygen/hydrogen/sulphur at parts-per-million levels), AMS 2750F pyrometry (±5.5°C furnace uniformity — more accurate than most food processing ovens), NADCAP heat treatment and NDE accreditation (third-party audited process certification not available in any other industry except nuclear), and 100% ultrasonic inspection per AMS 2631 (zone-by-zone scanning with calibration standards). The global aerospace forging market ($7.6B in 2023, growing at 7.2% CAGR to $14B by 2030) is dominated by two large US companies (Arconic — formerly Alcoa Forged Products, and Precision Castparts/Berkshire Hathaway) and several European specialists (Aubert & Duval France, Böhler Austria, VSMPO Russia/now sanctioned). India's entry into aerospace forging — led by Bharat Forge, Shivam Forge, and Aequs Aerospace — is supported by HAL's indigenous engine programs (Kaveri turbofan, Shakti helicopter engine) and the ambitious Indian defence indigenization mandate (75% defence procurement from Indian industry under the Aatmanirbhar Bharat programme by 2027).

HAL (Hindustan Aeronautics Limited — India's largest defence aerospace manufacturer, established 1940, Bengaluru headquarters, $3.2B revenue) is the primary Indian customer for aerospace forgings. HAL designs and manufactures: Tejas Light Combat Aircraft (LCA MK1A — GE F404-IN20 engine, 83 ordered by IAF, $6.7B contract; MK2 — GE F414 engine, 108 on order, first delivery 2026); ALH Dhruv Advanced Light Helicopter (Shakti/TM333-2B2 turboshaft engine, 350+ delivered to Army/Navy/Air Force/Coast Guard); HTT-40 (HAL's Basic Trainer Aircraft — PT6A-68C engine). HAL's Gas Turbine Research Establishment (GTRE, Bengaluru) develops the Kaveri engine (afterburner turbofan, 81 kN with afterburner — for Tejas MK2 eventually) using Hastelloy X equivalent forged combustion chamber casings and Nimonic 115 turbine blade blanks. DRDO's Aeronautical Development Establishment (ADE, Bengaluru) develops the Rustom-2 MALE UAV (medium altitude long endurance — 30-hour endurance, 7km altitude) using 7075-T73 aluminium structural forgings (AMS 4139) for wing spar and fuselage frame components. Shivam Forge supplies HAL and DRDO under the CEMILAC (Centre for Military Airworthiness and Certification) approved vendor framework, with AS9100 Rev D quality documentation and AMS-referenced material specifications.

The CFM LEAP engine (CFM International — GE Aviation 50% / Safran Aircraft Engines 50% — 50% market share on Boeing 737 MAX, 100% on Airbus A320neo, 100% on COMAC C919) is the world's bestselling commercial aero engine with 20,000+ on order and 17,000+ in service. Each LEAP-1A (Airbus A320neo, 28,000 lbf thrust) contains: a Ti-6Al-4V 3D-woven composite fan (CFM proprietary — but the hub forging and pitch-change bearings are titanium forgings), 3 stages of LPC blisk (bladed disk as single piece) in Ti-6Al-4V (AMS 4928), 10 stages of HPC blisk (stages 1–3 Ti-6Al-4V, stages 4–10 IN718 at increasing temperatures), combustor outer liner forging in Hastelloy X, HPT disk forging in ME3 superalloy (Rene 104), and 7 stages of LPT disk forgings in IN718 (stages 5–7) or Rene 77 (stages 1–4). Safran Aircraft Engines (Villaroche, France — CFM50% partner) manufactures the low-pressure turbine, combustor, and LEAP engine accessories — sourcing compressor disk forgings from approved forge shops in France (Aubert & Duval), USA (Precision Castparts), and increasingly India (Bharat Forge / HAL ToT). Shivam Forge's IN718 (AMS 5664) compressor disk blank forgings — with AMS 2750F Class 2 heat treatment and NADCAP UT inspection (under pursuit) — target the Safran/GE LEAP engine Indian supply chain development.
