Manufacturer, Supplier & Exporter of Incoloy 800H / 800HT Ferrule Fittings

Incoloy 800H / 800HT Ferrule Fittings are high-performance, corrosion-resistant components made from the upgraded versions of Incoloy 800. These alloys are specifically designed for enhanced strength and resistance to high-temperature oxidation, carburization, and thermal creep. Riddhi Siddhi Impex, a leading manufacturer and domestic supplier based in India, specializes in producing premium quality Incoloy 800H and 800HT ferrule fittings that meet international standards and cater to demanding industrial applications..

The primary distinction of Incoloy 800H and 800HT lies in their modified chemical compositions and heat treatments. These fittings exhibit superior mechanical strength at elevated temperatures, thanks to controlled carbon, aluminum, and titanium content. This makes them ideal for applications in heat exchangers, power plants, oil refineries, and chemical processing units. Riddhi Siddhi Impex ensures that every fitting is manufactured using precision-machining processes and rigorous quality checks.

Riddhi Siddhi Impex supplies Incoloy 800H / 800HT ferrule fittings to major Indian cities including Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru, Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Narmada, Ankleshwar, Navsari, Valsad, and Rajpipla. Their wide supply chain ensures timely delivery and seamless client support across India’s industrial zones..

The chemical composition of Incoloy 800H/800HT includes approximately 30–35% Nickel, 19–23% Chromium, with additions of Titanium and Aluminum that provide excellent structural stability during long-term exposure to high heat. The mechanical properties of these alloys—particularly their tensile strength, yield strength, and stress rupture resistance—make them ideal for systems that undergo thermal cycling or continuous high-temperature exposure.

Riddhi Siddhi Impex offers these fittings in both seamless and welded forms with NPT, BSP, BSPT, and custom threads. The company supports custom fabrication services, enabling clients to order fittings in precise dimensions and pressure classes. Their technical team works closely with engineers and procurement managers to ensure that the delivered products meet exact project requirements.
