Inconel 625 Square Rods
Inconel 625 square rods are premium nickel‑chromium‑molybdenum superalloy products manufactured, stocked, and exported by Rose Metal Industries, offering exceptional strength, corrosion resistance, and thermal stability for demanding industrial applications. Designed for environments where high stress, elevated temperatures, or aggressive chemical exposure is common, these square rods provide consistent dimensional accuracy and ease of machining for components such as fasteners, shafts, structural parts, and precision-engineered equipment..
The chemical composition of Inconel 625 includes a minimum of 58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium plus tantalum, with controlled amounts of iron, carbon, silicon, and manganese. This alloying ensures outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, making the rods suitable for use in marine, chemical, and petrochemical industries as well as for high-temperature applications.
Mechanically, Inconel 625 square rods exhibit high tensile strength (typically around 827 MPa), yield strength (~414 MPa), and elongation of 30–40%, which together provide excellent ductility, toughness, and structural integrity. The rods maintain these properties even at elevated temperatures up to approximately 980 °C, allowing them to perform reliably in turbine parts, heat exchangers, reactor components, and other critical industrial equipment.
These square rods are produced according to global standards such as ASTM B446 / ASME SB446, ensuring high quality and conformity to international specifications. They are available in various cross-sectional sizes and lengths, supplied in annealed or forged conditions, and accompanied by mill test certificates (MTC), chemical analysis, and mechanical property reports for quality assurance.
