Hastelloy N Bars and Rods are top-tier nickel-based alloy products celebrated for their outstanding resistance to high-temperature oxidation and corrosion, particularly in molten fluoride salt environments. Produced by reputable manufacturers like Semih Metals in Istanbul, Turkey, these bars and rods are crafted to meet the rigorous demands of industries such as nuclear power, chemical processing, and aerospace. With meticulous manufacturing practices and strict quality control, Hastelloy N products deliver reliability and durability, making them perfect for applications where standard alloys struggle under extreme thermal and chemical conditions.
The primary makeup of Hastelloy N consists of nickel (around 71%), along with notable amounts of molybdenum (16%), iron (5%), chromium (7%), and trace elements like silicon and manganese. This unique composition provides remarkable resistance to corrosion in molten fluoride salts, along with excellent thermal stability and mechanical strength. It retains its structural integrity even at high temperatures, boasting a tensile strength typically exceeding 690 MPa and good ductility. Additionally, the alloy features low creep rates and high resistance to stress-corrosion cracking, making it an excellent choice for long-term use in challenging environments.
