Alloy 22
Documentation:
CMI Alloy Data Sheet
Description:
Alloy 22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice
corrosion and stress corrosion cracking. It resists the formation of grain boundary
precipitates in the weld-heat affected zone making it suitable for use in the as-welded
condition. Alloy 22 has outstanding resistance to both reducing and oxidizing media and
because of its resistibility can be used where "upset" conditions are likely to occur. It
is proven to possess excellent weldability and high corrosion resistance as consumable
filler wires and electrodes. The alloy has proven results as a filler wire in many
applications. As filler wire use when other corrosion resistant wires have failed.
