Brief introduction:
It's a Ni-Fe-Cr alloy with additions of Mo，Cu and Ti.
It has excellent resistance to reducing and oxidizing acids, stress-corrossion cracking and localized attack such as pitting and crevice corrossion.And it especially resistant to sulfuric and phosphoric acids.
Used for chemical processing, pollution-control equipment, oil&gas well piping, nuclear fuel reprocessing, aid production and pickling equipment.
