Hastelloy Coils are an alloy resistant to corrosion, recognized for their outstanding performance in harsh chemical settings. Made up of different 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 preserve 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 not hold up.

Hastelloy Coils applications are as varied as the industries they serve, driven mainly by the aerospace, railway, construction and automotive industries 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 the 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 approach for joining Hastelloy coils thanks to its accurate heat management and reduced likelihood of sensitization and embrittlement. Alternative approaches such as MIG (metal inert gas) welding and SMAW (shielded metal arc welding) may also be employed when suitable precautions are taken.
Yes, there are particular factors to keep in mind when machining or fabricating Hastelloy coils. Hastelloy is a rugged alloy with elevated work hardening rates, meaning it calls for reduced speeds, deep cuts, and generous coolant while machining to limit work hardening and tool wear. Carbide tooling is advised, and machining should be performed at low speeds to avoid overheating. Follow-up steps such as stress relieving or annealing may be required to bring back material properties. Furthermore, Hastelloy coils ought to be cleaned carefully prior to fabrication to eliminate any contaminants that might compromise weld quality or corrosion resistance.
