Inconel Fasteners Supplier in Mumbai, India
Nicorex Alloys is an ISO 9001 and ISO 14001 certified importer, stockist, and supplier of Inconel fasteners in Mumbai, India. We stock grades 600, 601, 625, 718, and X-750 as hex bolts, nuts, studs, screws, washers, and threaded rods under ASTM F467, ASTM F468, and ASTM B637.
Inconel is a nickel-chromium superalloy. These alloys hold clamping force from cryogenic to 2200°F (1093°C), where standard steel fasteners fail. Products serve aerospace, oil and gas, chemical processing, power generation, nuclear, and marine industries. All shipments carry EN 10204/3.1B mill test certificates.

Available Grades of Inconel Fasteners
Inconel 600 Fasteners
Solid-solution strengthened with oxidation resistance to 2000°F (1093°C). Used for furnace bolting and nuclear reactor fasteners.
Inconel 601 Fasteners
High chromium (21 to 25%) gives oxidation resistance to 2200°F (1200°C). Used for thermal processing and exhaust system fasteners.
Inconel 625 Fasteners
The most widely used Inconel grade for corrosion-resistant fasteners. NACE MR0175 listed. Minimum tensile 930 MPa. It complies with ASTM F467/F468 and AMS 5666 standards.
Inconel 718 Fasteners
Precipitation-hardenable with higher strength than 625. Creep-rupture strength to 1300°F (704°C). NACE MR0175 compliant at 40 HRC max. AMS 5663 and API 6A718 standards govern this grade.
Inconel X-750 Fasteners
Precipitation-hardenable with strong relaxation resistance. Used for gas turbine bolting and nuclear reactor internals.
Industries and Applications of Inconel Fasteners
- Aerospace and Gas Turbines: Turbine disc bolts and exhaust studs use grades like 718 and X-750.
- Oil and Gas: 718 and 625 are used as wellhead stud bolts (API 6A718) and subsea fasteners.
- Chemical and Petrochemical: Reactor closure bolts and flange studs use 625 and 600 grades.
- Power Generation: Inconel grades 718 and 601 are used for turbine casing bolts and nuclear closure studs.
- Marine and Offshore: Grades 625 and 718 are used for platform bolting and seawater flange studs.
- Exhaust and Emissions: Inconel 625 and 601 are used for manifold studs and turbocharger bolts.
- Heat Treatment Equipment: Furnace bolts and retort studs use 600 and 601 grades.
