Alloy 75 Round Bars Manufacturer, Stockist and Exporter

Alloy 75 Round Bars, also known as Nimonic 75 bars, are nickel-chromium alloys that offer excellent mechanical strength and oxidation resistance. These bars are primarily used in applications that require high-temperature performance and corrosion resistance. They are ideal for use in environments such as gas turbines, heat-treatment equipment, and furnace components. The combination of strength and stability makes Alloy 75 a reliable material for industrial operations under extreme conditions.

One of the key features of Alloy 75 Round Bars is their exceptional oxidation resistance at temperatures up to 1000°C. This property allows them to retain their mechanical integrity even in harsh environments. The alloy’s balanced composition of nickel, chromium, and trace elements ensures consistent performance in both oxidizing and reducing conditions. Industries that require high-temperature applications often prefer Alloy 75 for its ability to withstand thermal stress without deformation.

The manufacturing process of Alloy 75 Round Bars involves precision-controlled melting, forging, and heat treatment processes. These steps are designed to enhance the alloy’s grain structure, tensile strength, and fatigue resistance. The round bars are available in a variety of sizes and diameters, allowing for flexibility in different engineering and fabrication projects. The material is also easy to machine and weld, making it suitable for customized components and assemblies.

In terms of chemical composition, Alloy 75 primarily contains nickel and chromium, with small additions of titanium and carbon. This composition provides the alloy with excellent resistance to oxidation and scaling. The titanium improves the alloy’s creep strength, while carbon contributes to hardenability. The balance between these elements ensures that the alloy maintains strength and ductility over a wide temperature range, making it ideal for high-stress components.

Mechanically, Alloy 75 Round Bars offer a remarkable combination of strength, hardness, and elongation. The alloy exhibits good tensile strength, moderate yield strength, and excellent ductility, allowing it to absorb stress and vibrations effectively. This makes it suitable for applications in jet engine components, exhaust systems, and high-temperature fasteners. The bars are also known for their stability and minimal creep deformation even under continuous high-stress conditions.

Alloy Alloy Round Bars

Alloy 75 Round Bars are available in various forms such as hot-rolled, cold-drawn, and centerless ground finishes. These different finishes enhance the surface quality and dimensional precision of the bars. They can be supplied in both custom-cut lengths and standard dimensions to meet the diverse needs of industries. The alloy’s versatility extends to its ability to be fabricated through different techniques, including forging, turning, and threading, depending on the application requirements.

Overall, Alloy 75 Round Bars are a perfect blend of strength, durability, and heat resistance. They offer outstanding performance in industries such as aerospace, chemical processing, power generation, and automotive. Their ability to perform under extreme thermal and mechanical stress makes them one of the most reliable materials for high-temperature structural applications. With proper maintenance and handling, these round bars ensure long service life and cost-effectiveness in demanding industrial environments.
