      Economic Considerations: Incoloy 825 is significantly cheaper because it replaces a large portion of nickel with iron. For oil and gas downhole tubing where sulfuric acid or CO2 is present but the extreme pitting resistance of 625 isn’t required, 825 is the most “value-engineered” solution.<\/p>\n<\/li>\n<\/ol>\n
