Grades: Inconel 625 (UNS N06625), Monel 400 (UNS N04400)
Inox Steel India is a manufacturer, supplier, and exporter of nickel alloy hex bars, supplying to chemical processing, marine, offshore, power, and high-performance engineering industries across India, GCC countries, the Middle East, Africa, Europe, and the Americas.
Nickel alloy hex bars are supplied in Inconel 625 and Monel 400 grades, manufactured in accordance with ASTM / ASME standards. These alloys are selected for applications requiring exceptional corrosion resistance, high-temperature strength, and reliability in aggressive environments.
With controlled melting, solution annealing, and dimensional processing, nickel alloy hex bars supplied by Inox Steel India provide uniform microstructure, consistent mechanical properties, and dependable performance in critical service conditions.
Nickel alloy hex bars are solid long products with a hexagonal (six-sided) cross section, manufactured from nickel-based alloys engineered to withstand corrosive media, high pressure, and elevated temperatures. The hexagonal profile enables positive tool grip and torque transmission, making these bars suitable for fasteners, fittings, and precision-machined components.
Nickel alloy hex bars are produced from alloy billets using hot rolling, forging, or cold drawing, followed by solution annealing or annealing to achieve the required strength, ductility, and corrosion resistance.
These properties make nickel alloy hex bars suitable for severe service and high-performance environments.
Nickel alloy hex bars are supplied in the following grades:
Materials are supplied as per ASTM B446 / SB446 (Inconel 625) and ASTM B164 / SB164 (Monel 400) specifications.
