Applications Alloy 825:
Alloy 825 is a nickel-iron-chromium alloy with molybdenum and copper added to it. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. The alloy is especially resistant to sulfuric and phosphoric acids. Used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
Applications Alloy C276:
Alloy C276 has a very good resistance to a variety of chemical process environments such as hot contaminated organic and inorganic media, chlorine, formic and acetic acids, acetic anhydride, seawater and brine solutions and strong oxidizers such as ferric and cupric chlorides. Alloy C276 has excellent resistance to pitting and to stress-corrosion cracking but it is also used in flue gas desulfurization systems for sulfur compounds and chloride ions encounted in most scrubbers. It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.

Titanium Grade 2 – UNS R50400
Applications Titanium Grade 2:
Titanium Grade 2 is a commercially pure Titanium (CP) and is the most commonly used type of Titanium for industrial applications. Titanium Grade 2 is used extensively for sea water piping, reactor vessels and heat exchangers in the (Petro)-chemical, Oil & Gas and Marine Industries. This is partly due to its low density and corrosion resistance and can be easily welded, hot and cold worked and machined.
