Product Details

Inconel 718 is precipitation hardened nickel alloy containing amounts of niobium and molybdenum. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF.  Alloy  718 seamless steel pipe is used in applications that require high strength and resistance to pitting corrosion.
