Alloy 625 Sheet, Bar, Plate, Coil - AMS 5599, 5666, N06625
Inconel® 625 is a nickel-based superalloy with excellent resistance to oxidation and corrosion, in conditions ranging from jet engine propulsion systems to chemical processing of oxidizing and reducing acids. The nickel-chromium matrix of Inconel® 625 is reinforced by the addition of molybdenum and niobium, which is alloyed through solid solution strengthening, and this allows it to maintain high strength and toughness at temperatures ranging from cryogenic up to 2000°F (1093°C). It is non-magnetic, austenitic, and displays high tensile strength, fabricability, and brazeability. Due to its high nickel content, this alloy is nearly immune to chloride ion stress-corrosion cracking and pitting, which is commonly found in metals in seawater applications like heat exchangers, fasteners, and cable sheathing.
