HASTELLOY^® C-22^® alloy Information*

A most versatile nickel-chromium-molybdenum-tungsten alloy available today with improved resistance to both uniform and localized corrosion
as well as to a variety of mixed industrial chemicals. The C-22 alloy exhibits superior weldability and is used as overalloy filler wire and
weld overlay consumables to improve resistance to corrosion.

Isocorrosion Curves^*

The isocorrosion diagrams shown on this page were plotted using data obtained in laboratory tests in reagent grade acids. These data should be used only as a guide. It is recommended that samples be tested under actual plant conditions.

*All test specimens were heat-treated at 2050°F (1121°C), rapid quenched and in the unwelded condition.
