Features:
254 SMO is a high performance austenitic stainless steel. Its high
alloying elements content imparts excellent resistance to uniform,
pitting and crevice corrosion, and stress corrosion cracking. It
was originally developed to withstand the corrosion of acids,
especially in the presence of halide ions, such as hydrochloric
acid, hydrofluoric acid, phosphoric acid, and sulphuric acid
contaminated with chlorides. In certain environments it is an
alternative to more expensive nickel alloys and titanium
alloys.
Applications:
Chemical processing equipment, pulp and paper industry bleaching equipment, desalination plant seawater piping, food and beverage industry, pharmaceuticals, and hydrometallurgy.
