Neptune Alloys is one of the most popular Nimonic Round Bars manufacturer that perform at very high temperatures due to specifications in nickel-chromium superalloys. The bars are very resistant to oxidation, thermal creep and corrosion properties that make them inseparable in airplane engines, nuclear engine, heat-treating machine and turbine systems subject to high stresses. They may be supplied in grades such as Nimonic 75, and grades Nimonic 80A and 90, hot rolled, forged, or bright-drawn, with optionally centerless grind-grounded pickled surfaces.
Our Nimonic round bars are produced to the standards of ASTM B637, BS HR1 and DIN 17752 and are exact and of the best quality in B2B technical jobs. The batches pass mechanical tests, ultrasonic tests, hardness tests, and grain structure tests in order to match high performance standards. Our products have all this customization by length, diameter, and the surface finish according to the particular specifications of the clients. Utilizing effective logistics and export channels we deliver Nimonic bars when required to engineering industries in India and other leading engineering centres world over.
Type of Sub-products
Nimonic 80 A Round Bar
This alloy is known for its strength and creep resistance at high temperatures. Used in aircraft turbine blades, fasteners, and high temperature springs, Nimonic 80A is precipitation hardened and exhibits excellent fatigue life under load. It’s supplied in both annealed and hardened conditions as per end use.
Nimonic 90 Round Bar
Nimonic 90 is a high strength, heat resistant alloy ideal for high performance aerospace and power generation components. It resists thermal creep and maintains integrity under intense pressure. Applications include turbine rotor blades, valve parts, and high pressure seals in extreme thermal conditions.
Frequently Asked Questions
What are Nimonic Round Bars typically used for?
Nimonic round bars are used in high-temperature applications such as gas turbines, exhaust systems, aerospace components, and nuclear reactors. Their ability to maintain strength and resist oxidation makes them reliable in environments above 700°C.
Which standards control the manufacturing of Nimonic Round Bars?
Depending on the grade, nimonic bars meet BS HR1, ASTM B637 and ISO 9723 standards. These standards ensure the correct mechanical properties, heat treatment conditions and chemical composition for industrial-grade applications.
Are custom sizes available for Nimonic Round Bars?
Yes, Nimonic bars can be custom-cut to specific lengths and diameters. Options include different surface finishes such as turned, polished, or ground. Full traceability, test certificates, and packaging standards are followed to meet engineering and procurement needs.
