Hastelloy Coils are a corrosion-resistant alloy known for their exceptional performance in aggressive chemical environments. Comprising various nickel-chromium-molybdenum combinations, Hastelloy coils offer high resistance to corrosion, oxidation, and stress corrosion cracking. Widely used in chemical processing, aerospace, and industrial applications, these coils maintain their integrity in extreme conditions, making them suitable for handling corrosive acids, alkalis, and other harsh chemicals. The versatility and durability of Hastelloy coils make them a preferred choice in critical environments where traditional alloys may fail.

Hastelloy Coils applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Hastelloy coils are used in 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 for their corrosion resistance, high temperature performance, and mechanical strength.
TIG (tungsten inert gas) welding is the primary recommended technique for joining Hastelloy coils due to its precise heat control and lower risk of sensitization and embrittlement. Other methods like MIG (metal inert gas) welding and SMAW (shielded metal arc welding) can also be used with proper precautions.
Yes, there are special considerations for machining or fabrication of Hastelloy coils. Hastelloy is a tough alloy with high work hardening rates, so it requires slow speeds, heavy cuts, and ample coolant during machining to minimize work hardening and tool wear. Carbide tooling is recommended, and machining operations should be conducted at low speeds to prevent overheating. Post-machining operations like stress relieving or annealing may be necessary to restore material properties. Additionally, Hastelloy coils should be cleaned thoroughly before fabrication to remove any contaminants that could affect weld quality or corrosion resistance.
