Luois Metals is your go-to manufacturer and supplier of **Hastelloy N Bars and Rods**, proudly based in Houston, USA. We focus on high-performance nickel-based alloys that are designed to thrive in extreme environments, especially in nuclear and molten salt applications. Hastelloy N stands out for its remarkable resistance to fluoride salts, making it a top choice for cutting-edge energy systems like molten salt reactors (MSRs) and nuclear fuel processing. At Luois Metals, we provide these bars and rods in a variety of diameters, tempers, and finishes, all while adhering to strict quality and performance standards to meet the needs of the most demanding industries.
When it comes to composition, **Hastelloy N Bars and Rods** are primarily made of nickel, with notable amounts of molybdenum (around 16%), iron (about 7%), and trace elements of chromium and other stabilizers. This alloy is exceptional in resisting corrosion from molten fluoride salts and maintains good mechanical strength and stability even at high temperatures—up to 700°C (1290°F). Additionally, Hastelloy N has low neutron absorption and excellent weldability, making it a perfect fit for components in nuclear reactors and related systems. Its well-rounded mechanical and corrosion-resistant properties ensure reliable long-term service in highly aggressive environments.
