For US procurement teams, an open die forging supplier is rarely selected on press tonnage alone. Heavy forgings for shafts, blocks, discs, hubs, rings and pressure-retaining components must combine sufficient deformation, controlled thermal history, sound internal quality, machining capability and documentation that survives an OEM or third-party audit. India has become a practical source for […]

Steam turbine rotors — the rotating assemblies that convert high-pressure steam energy into mechanical shaft rotation in power plants, industrial process applications, and shipboard steam turbines — contain the highest-value and most technically demanding forgings in the power generation industry. High-pressure (HP) rotors operate at 500–600°C in supercritical and ultra-supercritical plants and require CrMoV alloy [&h

300M (UNS K44220, AMS 6257) is the ultra-high-strength low-alloy steel used for commercial aircraft landing gear side struts, Boeing 737 and Airbus A320 main gear actuator housings, and defence structural applications where the highest possible strength-to-weight ratio in steel is required. At 280–300 ksi (1,930–2,070 MPa) minimum tensile strength in the fully quenched and tempered […]

9% nickel steel (UNS K81340, ASTM A353, ASTM A553) is the primary structural material for cryogenic LNG storage tank shells, LNG carrier primary barriers, and liquid nitrogen storage vessels — it maintains adequate toughness at -196°C (liquid nitrogen temperature) and -162°C (LNG temperature) where carbon steel and most low-alloy steels become catastrophically brittle. As India’s […]

Super duplex 2507 (UNS S32750, ASTM A182 F53) — the most widely used super duplex stainless steel in offshore subsea, North Sea topside, and aggressive chemical process applications — presents unique forging process challenges that go beyond standard stainless steel forging. Sigma phase formation during slow cooling through 600–900°C, ferrite-austenite phase balance requirements (35–65% ferrite), […]

Selecting the correct alloy steel for a critical forging — where failure carries safety consequences in aerospace, defence, nuclear, marine, or oil and gas service — requires understanding the relationship between alloy composition, heat treatment, achievable mechanical properties, and the specific failure modes the component must resist. This technical guide compares the most widely used […]

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 […]
