Ganpat Metal manufactures and supplies certified Alloy Steel F9 / WP9 (9% Cr 1% Mo) Round Bars conforming to ASTM A182 F9 / ASME SA182, ASTM A276. Alloy Steel F9 (9Cr-1Mo) provides enhanced oxidation and corrosion resistance compared to lower-chromium alloy steels. It is widely used in hydrocracking units, refinery piping, and petrochemical furnace coils up to 650°C.
Our ASTM A182 F9 round bars are produced under rigorous quality management, supplied in cold drawn, peeled, centerless ground, or forged rough-turned condition. Each bar is carefully heat treated to achieve optimum grain structure, superior straightness (≤ 1 mm/m), and uniform mechanical strength suitable for high-speed machining, valve components, pump shafts, and structural engineering fasteners.
We maintain extensive inventories from 3 mm to 500 mm diameter in standard mill lengths and custom cut-to-length billets with complete EN 10204 Type 3.1 Mill Test Certificates and third-party inspection support.
GM handles enquiries for ASTM A182 F9 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.
