Kolkata, India-headquartered Neil Metals is a renowned manufacturer and exporter of **Inconel Hex Bars and Rods**, providing precision-machined nickel–chromium superalloy stock in hex cross-sections. Meeting global standards like ASTM B166/B408, ASME SB166/SB408, and DIN, their hex bars cover 18 mm to 57 mm across flats, with finishes ranging from black and brown to bright, and detailed inspection for dimension and material integrity ([navgrahasteels.com][1]). Capitalizing on sophisticated production techniques and rigorous quality checks, Neil Metals delivers on schedule corrosion-resistant, high-strength hex bars to stringent applications in aerospace, chemical processing, power generation, and marine sectors.
**Inconel Hex Bars and Rods** are nickel–chromium-based superalloys with high nickel content (for example, Inconel 600 contains ≥ 72% Ni, 14–17% Cr, 6–10% Fe). Other grades such as Inconel 625 include molybdenum and niobium, whereas Inconel 718 and X‑750 contain titanium and aluminum for precipitation hardening ([en.wikipedia.org][2]). These alloys create a protective oxide that allows for oxidation and corrosion resistance at elevated temperatures, and maintain tensile strength over 500 MPa even at high service conditions ([en.wikipedia.org][2]). Hexagonal bars are manufactured within 18–57 mm A/F (11/16″–2¾″) and can be ordered in hot-rolled, cold-drawn, peeled, or polished finishes ([navgrahasteels.com][1]).

**Inconel Hex Bars and Rods** are employed widely in **high-temperature, corrosive environments**. They find application in **gas turbine components**, **combustion liners**, **heat exchanger components**, and **pressure vessel fittings** across the aerospace, petrochemical, and power-generation industries. In the maritime industry, they are utilized for **pump shafts**, **fasteners**, and **flare stack fittings** submerged in seawater. The hex shape facilitates easier gripping and machining for **custom parts**, providing greater structural strength and simpler handling in manufacturing processes ([navgrahasteels.com][1]). Other important applications are **chemical reactor internals**, **nuclear core parts**, and **industrial furnace components**, where their strength, resistance to oxidation, and accurate dimensional tolerances are essential ([en.wikipedia.org][2]).
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
