Hastelloy C22, designated as UNS N06022 (European equivalent W. Nr. 2.4602), is a high-performance nickel-chromium-molybdenum-tungsten alloy known for outstanding resistance to both oxidizing and reducing environments. Its unique chemical composition—typically containing around 20–22.5% chromium, 12.5–14.5% molybdenum, and 2.5–3.5% tungsten—provides robustness in aggressive media.

The Hastelloy C22 Round Bars offered by SMM Industries LLP are cylindrical rods manufactured from the nickel alloy C22 (UNS N06022). Produced in diameters ranging from a few millimeters up to hundreds of millimeters, in finishes such as hot-rolled, cold-drawn, bright polished or black finish, these bars are designed for precision use. The alloy’s microstructure remains stable over time, delivering excellent weldability and fabricability without compromising performance.

Mechanically, these round bars exhibit a tensile strength of approximately 690 MPa and a 0.2% offset yield strength of around 310 MPa, with elongation up to 45%. Their density is about 8.69 g/cm³, and they melt near 1399 °C, ensuring suitability for high-stress, high-temperature service.

Hastelloy C22 Round Bars combine a rare mix of properties that make them uniquely suited for harsh environments Exceptional Corrosion Resistance The alloy resists pitting, crevice corrosion, and stress-corrosion cracking in both oxidizing and reducing acids. High Mechanical Strength Strong yield and tensile strengths, coupled with good elongation, allow reliable performance under load. Temperature Stability Maintains mechanical integrity at elevated temperatures and during thermal cycles.

Fabrication Versatility Can be forged, machined, welded, and drawn without significant embrittlement. Long Service Life Its resistance to aggressive chemicals ensures durable performance even in corrosive process industries, reducing maintenance costs.

The versatile Hastelloy C22 Round Bars find extensive application in sectors where durability and corrosion resistance are critical:

• Chemical Processing: Used in reactors, vessels, pump shafts, and heat exchangers where exposure to strong acids and oxidizing agents is routine.

• Marine Engineering: Components like propeller shafts and structural fasteners benefit from C22’s resistance to seawater and salt spray.

• Oil & Gas: Employed in downhole equipment, manifolds and piping systems that handle sour gas, sulfur, and chlorides.

• Pharmaceuticals: Critical for equipment in systems that handle ultra-pure or highly corrosive fluids, complying with stringent ASME/ASTM design.

• Power Generation: Applied in scrubber systems, cooling towers, and turbine parts where sulfidation or oxidative gases threaten standard materials.

• Pollution Control: Ideal for flue gas desulfurization (FGD) scrubbers, waste-treatment plants, and selective leaching systems.
