Nickel alloys are very resistant to oxidation and corrosion and when heated form a thick, stable, passivating oxide layer, protecting them from further attack. Nickel alloys also retain their strength over a wide range of temperatures. This makes them particularly attractive for use in high temperature applications
Dimension of ASTM B564 Alloy 625 RTJ Flange. Inconel 625 Flanges are used in chemical processing equipment and piping. They are resistant to oxidizing and reducing media, resistant to high temperature and resistant to chloride ion stress cracking as well
