Elvis Nickel Alloys, a reputable manufacturer and supplier located in Houston, USA, specializes in high-performance Hastelloy C22 Tube Fittings designed for use in highly corrosive and chemically aggressive environments. Made from UNS N06022, these tube fittings offer exceptional resistance to both oxidizing and reducing agents, chlorides, and a variety of acidic substances. They come in different configurations, including male/female connectors, bulkhead unions, elbows, and tees, and meet international standards like ASTM B366 and ASME B16.11. Hastelloy C22 Tube Fittings guarantee leak-proof, high-integrity connections in critical systems across the chemical, marine, pharmaceutical, and waste treatment industries.
Hastelloy C22 Tube Fittings are made up of about 58% nickel, 20–22.5% chromium, 12.5–14.5% molybdenum, and 2.5–3.5% iron, along with some tungsten and cobalt. These fittings showcase impressive tensile strength (~690 MPa), yield strength (~283 MPa), and high elongation (~45%), ensuring robust mechanical performance. The alloy’s structure offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in mixed acid or chloride-rich environments. Hastelloy C22 maintains its mechanical integrity across a wide range of temperatures, promising stable and long-lasting performance in tough conditions.
