Hastelloy N (UNS N10003) boasts a chemical makeup of approximately **71% nickel**, **15-18% molybdenum**, and **6-8% chromium**, with iron kept to about **≤ 5%**. It also includes trace amounts of silicon, manganese, tungsten, copper, cobalt, aluminum, titanium, and a very low carbon content (around **0.04-0.08%**). ([HB SPECIAL ALLOY][1]) When in the annealed (solution treated) state, its mechanical properties typically show a tensile strength of about **450-500 MPa**, yield strength ranging from **150-250 MPa**, and an elongation at break of around **40-50%**, depending on the thickness of the plate. ([HB SPECIAL ALLOY][1]) Hastelloy N is known for its impressive strength, oxidation resistance, and minimal corrosion when exposed to molten fluoride salts at temperatures between **704-871°C** (approximately **1300-1600°F**).

The applications for Hastelloy N sheets and plates from Tanvir Nickel Alloys are extensive. They are used in the chemical process industries for equipment that handles hot corrosive salts, in components for nuclear reactors (particularly in molten salt systems), in furnace and heat treatment parts, and in high-temperature flue gas exchangers. This alloy is essential in environments where resistance to oxidation and fluoride salt corrosion is a must. Its unique blend of strength, corrosion resistance, weldability, and high-temperature performance makes Hastelloy N an excellent choice for projects in the energy and petrochemical sectors.
