Hastelloy alloy strip and coil products—particularly grades C276, C22, C2000, and C4—are high-performance nickel-based materials engineered for extreme corrosion resistance. These alloys are widely used in industries requiring durability in harsh chemical, marine, or thermal environments. Available in strip or coil form, they offer excellent formability and stability during fabrication and operation.
Outstanding resistance to strong oxidizers, acids, and chlorides
Excellent mechanical strength and thermal stability
Available in soft, half-hard, or full-hard tempers
Suitable for welding, deep drawing, and precision forming
Long service life in aggressive chemical environments
| Grade | Main Composition | Corrosion Resistance | Max Operating Temp (°C) | Typical Applications |
|---|---|---|---|---|
| Hastelloy C276 | Ni-Mo-Cr-Fe | Excellent in oxidizing & reducing environments | 1040 | Chemical reactors, flue gas scrubbers, waste treatment |
| Hastelloy C22 | Ni-Cr-Mo-W-Fe | Exceptional resistance to pitting, crevice & stress corrosion | 1250 | Heat exchangers, chemical tanks, process piping |
| Hastelloy C2000 | Ni-Cr-Mo-Cu | Enhanced resistance to oxidizing acids like nitric | 1100 | Pharmaceutical systems, pickling equipment, bleaching plants |
| Hastelloy C4 | Ni-Mo | Great resistance to chloride-induced stress cracking | 1038 | Nuclear waste processing, acid production |
These nickel alloy strips and coils are frequently used in chemical processing plants where resistance to hydrochloric, sulfuric, and nitric acid is critical. Common applications include storage vessels, reaction tanks, and heat exchangers.
Due to their non-reactive nature and ease of sterilization, Hastelloy grades are ideal for clean-room environments, including filter systems and sterilization trays.
C276 and C22 strips are widely used in flue gas desulfurization systems, scrubbers, and emission control ducts due to their ability to withstand acid condensates and aggressive gas mixtures.
In seawater and brine-rich environments, Hastelloy alloys maintain corrosion resistance even under high pressure and temperature conditions. Ideal for pumps, valves, and tubing systems.
| Form | Thickness Range (mm) | Width Range (mm) | Delivery Condition |
|---|---|---|---|
| Strip | 0.05 – 3.0 | 10 – 400 | Annealed, Hard, Slit Edge |
| Coil | 0.10 – 2.5 | Up to 600 | Coil Form, Oscillated or Pancake |
While both are highly corrosion-resistant, C22 offers improved resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in oxidizing environments, compared to C276.
Yes, all grades mentioned—C276, C22, C2000, and C4—are weldable using appropriate techniques and filler metals, typically using TIG or MIG welding.
Depending on the grade, maximum service temperatures range from 1038°C (C4) to 1250°C (C22). Always confirm based on specific alloy data sheets.
Hastelloy coils are used across chemical processing, power generation, offshore oil & gas, marine engineering, food/pharma equipment, and air pollution control sectors.
No, Hastelloy alloys are generally non-magnetic, making them suitable for applications requiring minimal electromagnetic interference.
Hastelloy nickel alloy strip and coil products—especially grades C276, C22, C2000, and C4—are trusted in industries where reliability and corrosion resistance are critical. Their high-performance characteristics make them the preferred choice in demanding environments involving heat, pressure, and aggressive chemicals.
