Nickel Alloy Steel Flange ASTM B564 Alloy 625 UNS N06625 Aerospace
Overview
Alloy 625,inconel 625 flange,UNS N06625 flange is a nickel-chromium-molybdenum alloy used for its high strength, high toughness and excellent corrosion resistance. Ideally suited for use in large atmospheres subject to heat and pressure. Alloy 625,UNS N06625 derives its strength from the strengthening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition also provides a considerable level of general corrosion resistance.
Characteristic of Nickel Alloy Steel Flange
Corrosion resistance: It has excellent corrosion resistance, able to resist a variety of corrosive media, such as acid, alkali, brine and so on.
High-temperature strength: It still maintains high strength and durability under high-temperature environment.
Heat resistance: It is able to work for a long time in a high temperature environment, with good heat resistance.
