ASTM B622 UNS NO6022 Hastelloy C22 Low Carbon Nickel Alloy Seamless Tubes
YuHong Group as one of the leading suppliers in China to supply nickel alloy seamless pipes and tubes,etc.,we have many experiences in exporting.
ASTM B622 This specification covers seamless pipe and tube of nickel and nickel-cobalt alloys.
Alloy C22 is commonly referred to by the tradename Hastelloy C22 and the universal designation UNS N06022. It is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt.
Distinctive Characteristic
Oxidation Resistance
C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250°F.
Corrosion Resistance
Alloy C22 is one of the most corrosion-resistant alloys available, even outperforming C276 and 625. It is resistant to almost all reducing and oxidizing environments, including strong oxidizers, seawater, and organic acids. In addition, C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
