Neptune Alloys is a top manufacturer of Haynes Round Bar super alloy bars that are made to the high industrial performance standard and are suitable in extreme conditions of heat, oxidation and stress. Haynes alloys like Haynes 25, Haynes 230 and Haynes 282 which are cobalt-based or nickel-based alloys exhibit good strength, high thermal and corrosion resistance. The turbines in the aerospace, components of the jet engine, nuclear reactors, heat exchangers, and industrial furnace systems commonly employ these bars. Depending on grade Haynes bars provide creep resistance in excess of 1000 C and in surface finish, ground, bright-annealed or black.
In the case of business-to-business application, we offer haynes round bars, which are AMS, ASTM, and ASME compliant and are complete traceable with full inspection verification documentation. In order to ensure the structural reliability in the stress environment, every batch passes a rigorous testing procedure, which involves tensile, ultrasonic, and hardness tests. Custom bar lengths, diameters, and finish allow products, used to the highest precision of aerospace or industrial project specifications to be ordered, to satisfy the requirements of clients. With a strong manufacturing and export logistics we supply Haynes bars to the turbine OEMs, aerospace contractors and chemical process industries throughout India and across Globe
Type of Sub-products
Haynes 25 Round Bar
A cobalt based alloy with outstanding high temperature strength and oxidation resistance, ideal for jet engine combustion cans, afterburner components, and exhaust parts. With excellent hot hardness, it performs well above 1000°C.
Haynes 230 Round Bar
Designed for industrial furnace parts, heat exchangers, and chemical reactors, this nickel chromium tungsten alloy offers superior thermal stability and fabricability in long duration service under oxidizing conditions.
Frequently Asked Questions
What are Haynes round bars used for?
Haynes round bars are used in aerospace turbines, combustion systems, heat exchangers, marine exhausts, and chemical processing where high temperatures and oxidation resistance are critical for long-term durability.
Can Haynes bars be customized in size and finish?
Of course. We provide custom lengths, widths, and finishes, including polished, centerless ground, peeled, and hot-rolled. Customers can also specify heat treatments based on their operating environment or design application.
What makes Haynes alloys different from Inconel or Hastelloy?
Haynes alloys offer superior thermal resistance and creep strength at very high temperatures, often beyond what Inconel or Hastelloy can handle. They are preferred in advanced turbine engines and heat-intense zones.
