Description: The composition of this weld metal is the same as that deposited by AFM E330-16,
except that carbon ranges from 0.35 to 0.45 percent. AFM E330H-16 is primarily
for the welding and repairing of high alloy heat and corrosion resistant
castings of the same general composition which are designated HT by the Alloy
Castings Institute. This composition can be used to 2100¡ÆF (1150¡ÆC) in
oxidizing atmospheres and at 2000¡ÆF (1090¡ÆC) in reducing atmospheres. However,
high-sulfur environments may adversely affect performance at elevated
temperature.
