1. About Inconel 725 round bar brief introduction
Alloy 725 was developed from Alloy 625 by adding strengthening elements to enhance its mechanical properties. The properties of Nickel alloy 725 are useful for a wide range of applications that require outstanding corrosion resistance along with high strength. The alloy is used in sour gas service where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide.
Alloy 725 is also attractive for high strength fasteners in marine applications, where it resists corrosion, pitting and crevice attack in sea water.
