GH3625 (Inconel 625 Equivalent) Strip Offshore & Chemical Processing Corrosion Resistant

GH3625 is a nickel-chromium-molybdenum superalloy that serves as the Chinese equivalent to Inconel 625, offering exceptional corrosion resistance, high strength, and outstanding fabrication characteristics. This versatile alloy strip is particularly valued in offshore oil & gas, chemical processing, and marine engineering where resistance to pitting, crevice corrosion, and stress-corrosion cracking is critical.

Engineered to withstand some of the most aggressive environments, GH3625 maintains excellent mechanical properties from cryogenic temperatures up to 980°C (1800°F), making it a premium choice for demanding industrial applications.
