Nickel Alloy C22 pipe is a fully austenitic nickel-based superalloy that's cost-effective for clients seeking ease of forming combined with superior corrosion resistance. Also known as Inconel® 22 and Hastelloy® C22, this material is highly ductile, making cold forming easier. Inconel® 22 features resistance to an array of attacks from corrosion, pitting, crevice corrosion, intergranular, and stress corrosion cracking. Both cost effective and versatile; Inconel® 22 is used by a wide variety of industries.

Alloy C22 Pipe is available in Seamless or Welded from Size ranges 1/8" up to 26". Listed below are common sizes. Please contact for sizes not listed.

Additional Information N/A Common applications include chemical processing, paper and pulp, oil and gas, pesticide production, sour gas services, and waste incinerators. Providing considerable resistance at elevated temperatures, Inconel® 22 has been adopted for nuclear fuel reprocessing, flue gas desulfurization and seawater-based applications.

With the nickel as its primary base, Inconel® 22 alloy includes a chemical composition of 20-22.5% Cr, 12.5-14.5% Mo, a maximum of 2.5% Co, 2.5-3.5% W, and 2-6% Fe. For annealing treatment, temperature ranges should remain between 2020 and 2150 ºF. Inconel® 22 is suited for applications that require superior performance at elevated temperatures and for its full spectrum of anti-corrosion characteristics.
