SA Alloy 825 SAW Arc Submerged




SA Alloy 825

 
CATEGORY 
TYPE 
Nickel - Chromium - Molybdenium - Copper alloy for SAW welding.
APPLICATIONS 
The excellent corrosion-resistant 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.
PROPERTIES 

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. SA Alloy 825 is best to be used with FL 839 flux.
