Hastelloy N is a nickel-based alloy that mainly consists of about 71% Nickel, 16% Molybdenum, 5% Iron, along with trace amounts of Chromium, Silicon, and Manganese. This alloy is particularly resistant to high-temperature fluoride salts and shows good oxidation resistance in air. In terms of mechanical properties, Hastelloy N Bars and Rods boast impressive tensile strength, typically around 690 MPa or more, along with good ductility and structural stability at temperatures reaching up to 800°C. It’s also recognized for its excellent weldability and resistance to thermal shock, making it a great choice for extreme service conditions.

Yes, Hastelloy N rods can be welded using standard welding techniques, including TIG and MIG welding. Preheat and post-weld heat treatment may be required for optimal results.
Hastelloy N rods are available in various sizes, typically ranging from 1/8" to 3" in diameter. They come with finishes such as cold drawn, bright annealed, or polished, depending on the application.
Hastelloy N bars offer exceptional corrosion resistance, particularly in high-temperature environments. They also exhibit excellent strength, thermal stability, and resistance to oxidation and carburization.
Hastelloy N Bars and Rods find extensive use in nuclear reactors, especially in molten salt reactor (MSR) systems, thanks to their exceptional resistance to fluoride salt corrosion. They’re also utilized in the chemical industry for handling aggressive substances like hot acids and halide environments. In the aerospace sector, these materials are crucial for high-temperature components that need to withstand oxidation and corrosion. Other applications include heat exchangers, pressure vessels, piping systems, and equipment that face extreme thermal and chemical stress, ensuring long-lasting reliability even in the toughest operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
