Nickel-Chromium-Molybdenum alloyed strip for cladding overlay applications.
SA Alloy 825 is a nickel-iron-chromium-molybdenum-copper cladding alloy for use in extremely corrosive environments.
Fully austenitic weld metal with high resistance against stress corrosion cracking and pitting in media containing chloride ions. Good corrosion resistance against reducing acids due to the combination of Ni, Mo and Cu. Sufficient resistance against oxidizing acids. The weld metal is corrosion resistant in sea water. The nickel content of this alloy makes it resistant to chloride-ion stress-corrosion cracking. Additions of
molybdenum and copper give alloy 825 resistance to pitting and to corrosion in reducing acid environments such as sulphuric or phosphoric acid solutions. The alloys chromium content gives it resistance to various oxidizing environments, such as nitrates, nitric acid solutions and oxidizing salts. The excellent corrosionresistant properties of Alloy 825 make the alloy a suitable choice for a variety of difficult applications. Uses
include fabricated equipment found in chemical and petro- chemical processing, pulp and paper manufacturing, flue gas desulphurization systems and metal pickling operations. SA Alloy 825 strip is developed for cladding lower alloyed or steel parts to obtain protection against the earlier mentioned attacs for high quality tank and apparatus construction in the chemical industry.
