Hastelloy Coilsare a corrosion-resistant alloy recognized for their outstanding performance in harsh chemical settings. Made up of various nickel-chromium-molybdenum blends, Hastelloy coils provide strong resistance to corrosion, oxidation, and stress corrosion cracking. Commonly employed in chemical processing, aerospace, and industrial applications, these coils retain their integrity under extreme conditions, making them well-suited for handling corrosive acids, alkalis, and other aggressive chemicals. The adaptability and durability of Hastelloy coils establish them as a favored option in critical settings where conventional alloys may fail.

Hastelloy Coils find use across a wide range of applications, matching the many industries they support, led chiefly by the aerospace, railway, construction and automotive sectors along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Hastelloy coils serve chemical processing, aerospace, oil and gas, pharmaceuticals, power generation, water treatment, marine and shipbuilding, food and beverage processing, environmental protection, and pulp and paper industries thanks to their corrosion resistance, strong high temperature performance, and mechanical strength.
TIG (tungsten inert gas) welding stands as the main recommended method for joining Hastelloy coils, thanks to its accurate heat regulation and reduced likelihood of sensitization and embrittlement. Alternative approaches such as MIG (metal inert gas) welding and SMAW (shielded metal arc welding) are also viable when appropriate precautions are taken.
Yes, distinct factors come into play when machining or fabricating Hastelloy coils. Being a rugged alloy with elevated work hardening rates, Hastelloy demands slow speeds, heavy cuts, and generous coolant throughout machining to keep work hardening and tool wear to a minimum. Carbide tooling is advised, and machining should be performed at low speeds to avoid overheating. Follow-up operations such as stress relieving or annealing may be required to bring back the material’s properties. On top of that, Hastelloy coils should be cleaned carefully prior to fabrication to eliminate any contaminants that might compromise weld quality or corrosion resistance.
