Ganpat Metal manufactures and supplies Stainless Steel Round Bars in Grade 304, 304L, 316, 316L, 310S, 321 and 347 conforming to ASTM A276 / ASME SA276 and ASTM A479. As one of India’s leading stockists and manufacturers, we provide high-precision stainless round bars engineered for rotating machinery shafts, valve spindles, pump shafts, threaded fasteners, marine hardware, and structural engineering components.
Our stainless steel round bars are produced via modern electric arc melting (EAF/AOD) and refined with ladle furnace treatment to ensure clean steel chemistry, low inclusions, and uniform isotropic grain structure. We offer diverse surface conditions including black hot-rolled, annealed & pickled, rough-turned peeled, and precision centerless-ground finishes.
Sizes range from 3 mm to 500 mm in diameter, available in standard 3-meter and 6-meter lengths or custom cut-to-length billets with deburred chamfered ends and full EN 10204 3.1 certification.
GM handles enquiries for Stainless Steel 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.
