What is Incoloy 825 material?
INCOLOY 825 alloy (UNS N08825/W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The chemical composition of the alloy is designed to provide excellent resistance to a wide range of corrosive environments.
What is the ASTM standard for Inconel 825?
ASTM B423 UNS N08825 Alloy 825 Welded Pipe and Cold Drawn Annealed Incoloy 825 Pipe Suppliers. Incoloy 825 is one of the most effective alloy choices for harsh environments. It performs well in a variety of climates, especially in terms of general and localized corrosion, which makes Incoloy WERKSTOFF NR the best choice.
What is the difference between Inconel 625 and incoloy 825?
Inconel 625 is often used in sour gas service due to its good resistance to stress corrosion cracking and pitting, while incoloy 825 is often used in crude oil service due to its good corrosion resistance in sour environments.
What is Inconel 625 used for?
Some applications require the strength and corrosion resistance of INCONEL 625 alloy, such as bubble caps, piping, reaction vessels, distillation columns, heat exchangers, transfer piping and valves.
