COMMON TRADE NAMES: Inconel® 625, Sanicro® 625
Alloy 625 is a nickel-chromium-molybdenum solid solution strengthened alloy with a nominal chemical composition of 61% nickel, 22% chromium, and 9% molybdenum. It is commonly referred to by the tradename Inconel® 625 and the universal designation UNS N06625. Alloy 625 provides superior corrosion resistance in aggressive environments coupled with excellent strength and weldability.
Alloy 625 is a versatile alloy used in many different applications, including the chemical process industry, aerospace, food processing, electronics, and nuclear power generation. Alloy 625 is used extensively to clad wetted surfaces of oil and gas equipment to protect against corrosion by H2S, CO2 , chlorides, and other aggressive media. Its elevated temperature oxidation resistance makes it a good choice for heat-treating fixtures, furnaces, incinerators, and other high-temperature equipment. CRA offers specialty alloy 625 seamless pipe & tube for use in multiple industries and applications, including:
