What are Inconel 625 Pipes & Tubes?
Inconel 625 Pipes & Tubes are a nickel-based superalloy product distinguished by their exceptional resistance to a broad range of corrosive media. The alloy's unique composition, which includes significant amounts of chromium and molybdenum, provides outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking, especially in chloride-rich environments like seawater. With the ability to maintain its mechanical properties from cryogenic temperatures up to 1800°F (982°C), our Alloy 625 Pipe and Alloy 625 Tube are the ideal choice for applications requiring high performance in severe conditions.
