The commercial forms of nickel and nickel-base alloys are fully austenitic and are used/selected mainly for their resistance to high temperature and aqueous corrosion.
The nickel-chromium and nickel-chromium-iron series of alloys led the way to higher strength and resistance to elevated temperatures. Today they also form the basis for both commercial and military power systems.
Some High-Temperature Variants include:
Some Corrosion-Resistant Variants in the Ni-Cr-Fe System include:
Alloy 625 - The addition of 9% Mo plus 3% Nb offers both high-temperature and wet corrosion resistance; resists pitting and crevice corrosion
Iron-Nickel-Chromium Alloys
This series of alloys has also found extensive use in the high-temperature petrochemical environments, where sulfur-containing feedstocks (naphtha and heavy oils) are cracked into component distillate parts. Not only were they resistant to chloride-ion stress-corrosion cracking, but they also offered resistance to polythionic acid cracking. Some alloys of commercial importance include:
