Rectangle Polished Inconel 625 Nickel Based Alloy Pipe for Jet engine
Inconel 625 is a nickel-based super alloy that possesses excellent resistance to oxidation and corrosion in a broad range of environments. Additionally this alloy has outstanding strength and toughness at temperatures ranging from cryogenic to 2000°F. This alloy possesses a high degree of formability and shows better weldability than many other highly alloyed nickel based materials.
