Titanium Forging Manufacturer India: Aerospace and Industrial Applications


Titanium forging in India — producing Ti-6Al-4V Grade 5 (UNS R56400, AMS 4928) and commercially pure titanium (CP Grade 1/2/4, ASTM B381) forgings for aerospace structural, oil and gas industrial, marine, and hydrogen electrolyser applications is a growing domestic capability driven by Atmanirbhar Bharat aerospace manufacturing goals and the global VSMPO titanium supply disruption following Russia’s invasion of Ukraine. Vinir’s titanium forging capability, combined with controlled-atmosphere heating (alpha case prevention), NABL OES titanium chemistry testing, and AS9100D quality management, positions it as a domestic Indian titanium forging manufacturer for both aerospace programme supply and industrial applications.

India’s titanium forging capability has historically been concentrated at government facilities: MIDHANI (Mishra Dhatu Nigam, Hyderabad) has supplied Ti-6Al-4V forgings for HAL and ISRO programmes. The growing volumes required by Tejas LCA production, Dhruv ALH fleet expansion, DRDO missile programmes, and ISRO’s Gaganyaan spacecraft are stretching MIDHANI’s capacity creating an opening for AS9100D-certified private sector Indian titanium forging manufacturers.

Alpha case control — preventing the oxygen-enriched brittle surface layer that forms on titanium heated in the presence of oxygen is the defining quality challenge in titanium forging and is the primary differentiator between a technically capable titanium forge shop and one that simply heats and presses titanium.
Vinir’s alpha case control procedure: nitrogen gas purge of the heating furnace before each titanium heat (displacing atmospheric oxygen to below 10 ppm), protective coating on complex-geometry titanium forgings where nitrogen purge alone may not fully protect interior surfaces, and post-machining etch inspection at 10× magnification of all finished surfaces.

The VSMPO disruption — following Western aerospace OEM decisions to exit Russian titanium supply after Russia’s 2022 Ukraine invasion created meaningful supply chain pressure on the global aerospace titanium forging community. TIMET and ATI (the US primary alternatives) have been running at maximum capacity with extended lead times. Aerospace OEM procurement teams are actively qualifying previously secondary sources including Indian private sector forge shops. Vinir sources AMS 4928 billet from TIMET and ATI – eliminating Russian material from its titanium supply chain.

Industrial titanium forging — CP Grade 1 and Grade 2 tubesheets for marine seawater heat exchangers, Grade 2 flanges for SWRO desalination systems, and Ti-6Al-4V structural fittings for offshore subsea applications represents a complementary demand to aerospace. For industrial titanium applications, ASTM B381 / ASME SB-381 specifications are used rather than the more demanding AMS 4928, allowing industrial titanium forgings to be produced at lower cost while maintaining corrosion resistance benefits.

Frequently Asked Questions

1.What is the forging temperature window for Ti-6Al-4V and why is it more restrictive than for steel?+
Ti-6Al-4V should be forged in the temperature range 870–980°C for sub-beta transus (conventional) processing. The beta transus temperature is approximately 995°C for Ti-6Al-4V. Forging above the beta transus produces a coarse, transformed beta microstructure adequate for some structural applications but with lower fatigue resistance than the sub-beta bimodal microstructure used for aerospace. Below approximately 870°C, the rapidly increasing flow stress exceeds practical press capacity for most components. This gives a forging window of approximately 125°C narrower than the 200–300°C window typical for alloy steel but wider than the 86°C window for Inconel 718.
2.What is MIDHANI and what role does it play in Indian titanium forging supply?+
MIDHANI (Mishra Dhatu Nigam Limited) is a Government of India enterprise under the Ministry of Defence India’s premier specialty metals manufacturer, producing titanium, nickel superalloys, cobalt alloys, and specialty steels for defence and aerospace applications. MIDHANI produces titanium sponge, titanium billet, and some titanium forgings at its Hyderabad facility. Private sector AS9100D manufacturers can procure MIDHANI titanium billet and produce forgings from it combining India-domestic billet with AS9100D private sector forging manufacturing quality. Full Atmanirbhar Bharat titanium forging supply chains would combine MIDHANI billet with AS9100D private sector forge shop manufacturing.
3.What AMS 2154 immersion UT class is required for Ti-6Al-4V aerospace forgings?+
AMS 2154 defines four ultrasonic inspection classes Class A, AA, AAA, and AAAA with progressively more stringent acceptance criteria. Class A is the baseline for most structural titanium forgings. Class AA applies to rotating engine components (compressor discs, fan discs) where an undetected defect could cause catastrophic engine failure it rejects smaller indications than Class A, requiring higher inspection sensitivity and more precise scanning procedures. For HAL aeroengine disc applications, Class AA is mandatory. For structural airframe fittings, Class A is typically sufficient.
4.How does the VSMPO supply disruption create specific opportunities for Indian titanium forging manufacturers?+
Before 2022, VSMPO-AVISMA supplied approximately 40% of Boeing’s titanium and approximately 60% of Airbus’s. Following Western aerospace OEM decisions to exit Russian titanium supply, both TIMET and ATI (the US primary alternatives) have been running at full capacity with extended lead times. Aerospace OEM procurement teams have been actively qualifying previously secondary sources including Indian titanium processors (MIDHANI, TATA Advanced Materials). Indian private sector forge shops who source AMS 4928 billet from TIMET or ATI and produce Ti-6Al-4V forgings with AS9100D quality can access the global aerospace titanium supply chain in a way that was not practically possible when VSMPO dominated the market.
5.What is the industrial titanium forging market in India and what categories does it include?+
India’s industrial titanium forging demand includes: CP Grade 2 tubesheet forgings for marine seawater heat exchangers used in naval vessels (Mazagon Dock, GRSE) and offshore installations (ONGC, Reliance); CP Grade 1 and Grade 2 nozzle and flange forgings for SWRO desalination plants (being built under Jal Jeevan Mission); Ti-6Al-4V structural fittings for offshore subsea structures; and CP Grade 1 tubesheet forgings for PEM electrolysers in India’s green hydrogen programme (NTPC Green Energy, ACME Solar). Total Indian industrial titanium forging demand is estimated at 200–500 tonnes per year growing at 15–20% annually as India’s offshore, desalination, and green hydrogen infrastructure expands.
