Hastelloy B3 alloy, UNS N10665, resistance to hydrochloric acid and other strongly reducing chemicals but has poor corrosion resistance to oxidizing chemicals and in the presence of ferric or cupric salts. In addition, Hastelloy B2 has excellent resistance to pitting and stress corrosion cracking. However B2 has little chromium, and it should NOT be used with oxidizing media in the presence of salts.

Hastelloy C22 alloy, UNS N06022, has better overall corrosion resistance in oxidizing corrosives than C-276 and Inconel 625 alloys due to the higher chromium content. Outstanding resistance to localized corrosion and excellent resistance to stress corrosion cracking. This alloy has limited availability and can be made into fastener in larger diameters only (1/2" and greater in size).

HASTELLOY C2000
Hastelloy C2000 alloy, UNS N06200, is a corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or re-ducing environments. Due to the addition of copper and the high content of chromium, it has enhanced corrosion resistance to sulfuric acid and process streams contaminated with ferric ions. In addition it has excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy.
