Ganpat Metal manufactures and supplies High-Temperature Inconel Round Bars in Grades 600, 625, 718 and X-750 conforming to ASTM B166, ASTM B446, ASTM B637 and AMS aerospace specifications. Inconel nickel-chromium-based superalloys are designed to operate under extreme environmental conditions of mechanical stress, cyclic thermal fatigue, aggressive oxidation and corrosive chemical attack.
Inconel 600 serves in furnace parts and chemical equipment up to 1175°C. Inconel 625 provides high fatigue strength and pitting resistance in seawater without post-machining heat treatment. Inconel 718 and X-750 are precipitation-hardenable superalloys that achieve tensile strengths up to 1240 MPa (180 ksi) with exceptional creep-rupture performance for turbine rotors, high-pressure subsea valves, and rocket engines.
Our Inconel round bars are available from 4 mm to 350 mm in diameter in annealed, solution treated, or precipitation age-hardened conditions with 100% ultrasonic testing and complete EN 10204 3.1 certification.
GM handles enquiries for Inconel Round Bars where buyers need to match round bar diameters, machining tolerances (h9, h11, k12), and material grade to engineering drawings or purchase specifications. The supplied range covers precision cold drawn, peeled, centerless ground, and forged round bars beginning from 3 mm up to 500 mm diameter, with cut-to-size billet and pre-machined options.
Grade selection should be based on the required mechanical properties, core hardness, chemical composition, and operating temperature conditions of the application. Buyers should also confirm the applicable standard specification (ASTM / ASME / DIN / EN), delivery condition (annealed, solution treated, or quenched & tempered), NDT testing (ultrasonic / PMI), and mill documentation before finalizing an order.
