Ganpat Metal manufactures and supplies Monel Round Bars in Monel 400 (UNS N04400) and Monel K-500 (UNS N05500) conforming to ASTM B164, ASTM B865, ASME SB164 and Federal Specification QQ-N-286. Monel nickel-copper solid-solution alloys are the global benchmark for non-ferrous marine and chemical hardware.
Monel 400 offers unmatched resistance to rapidly flowing seawater, marine atmospheric corrosion, hydrofluoric acid, and strong caustic alkalis while retaining outstanding toughness from sub-zero cryogenic levels up to 550°C. Monel K-500 adds precipitation-hardening aluminium and titanium, multiplying yield strength up to 690 MPa while preserving non-magnetic characteristics down to -100°C.
We supply Monel round bars from 6 mm to 300 mm diameter in cold drawn annealed, stress relieved, and precipitation age-hardened conditions, widely used for marine propeller shafts, pump shafts, subsea valve stems, and downhole drill collars.
GM handles enquiries for Monel 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.
