High Temperature Resistance Alloy Inconel N06625 Nickel Alloy 625 Tubing Inconel 625 Pipe
The safe operating temperature range of alloy 625 nickel tubing spans from -238℉ (-150℃) to up to 1800℉ (982℃), so it can be used in a wide spectrum of applications that require exceptional corrosion resistance characteristics.
Variable temperatures are not the only thing that the alloy 625 nickel tubing can withstand, as the same applies for variable pressures and very harsh environments that induce high rates of oxidation. In general, it finds application in sea-water applications, the chemical processing industry, the nuclear energy field, and also the aerospace sector.Because of the metal's high Niobium (Nb) levels as well as its exposure to harsh environments and high temperatures, there was concern about the weldability of Inconel 625. Studies were therefore conducted to test the metal's weldability, tensile strength and creep resistance, and Inconel 625 was found to be an ideal choice for welding
As it is evident from the latter especially, the alloy 625 nickel tubing is also very resistant to cracking, rupture and creeping damage, featuring high tensile strength and extraordinary corrosion versatility.
