Hastelloy C22 Hexagon Bar

Product Details

By virtue of its contents of chromium, molybdenum, tungsten and controlled iron, this alloy exhibits excellent resistance to both oxidizing and reducing acid environments, as well as those containing mixed acids. It is particularly useful for resistance to pitting and crevice corrosion in acid-halide environments. Applications include the chemical processing, pollution control, flue gas desulfurization, waste incineration and pulp and paper processing industries.

STANDARD PRODUCT FORMS
Sheet, strip, plate, round bar, flat bar, forging stock,hexagon and wire.
