Direct Manufacturer of Inconel 625 Bars, Full Range of Inconel 625 Round Bar Specifications

Inconel 625 (UNS N06625) is an austenitic nickel-based superalloy. Despite being developed for high-temperature strength, its high-alloy composition offers excellent corrosion resistance against various oxidizing and non-oxidizing environments. It boasts superior wear resistance to oxidation and corrosion under a range of corrosive conditions, including jet engine environments and numerous other corrosive conditions, in aerospace and chemical processing applications. The alloy maintains exceptional strength and toughness over a temperature range from low temperatures up to 2000°F (1093°C). The NO625 alloy also exhibits excellent fatigue resistance, deriving its strength from the solid-solution strengthening effects of molybdenum and niobium in the nickel-chromium matrix.

Properties of Inconel 625 Alloy

Excellent mechanical properties at both relatively low and high temperatures.

Excellent resistance to pitting, crevice, and intergranular corrosion.

Almost completely unaffected by chloride-induced stress corrosion cracking.

Highly oxidation-resistant at temperatures up to 1050°C.

Excellent resistance to acids such as nitric acid, phosphoric acid, sulfuric acid, and hydrochloric acid, as well as alkalis, allows for the construction of thin, high-heat transfer structural components.
