inconel625 steel bar forged round bar round steel UNS NO6625 bar flaw detection qualified.

‌Inconel625 is a high-performance nickel-based alloy with excellent corrosion resistance, oxidation resistance and high-temperature strength. It is widely used in aerospace, chemical industry, marine engineering and nuclear energy. ‌‌

The main chemical components of Inconel625 include nickel (Ni), chromium (Cr), molybdenum (Mo), niobium (Nb) and other elements. The nickel content is usually between 58% and 71%, providing good corrosion resistance and high-temperature performance; the chromium content is about 20% to 23%, which enhances the corrosion resistance and oxidation resistance of the alloy; the molybdenum content is between 8% and 10%, which helps to improve the strength and pitting resistance of the alloy; the niobium content is between 3.15% and 5%, which further improves the strength, hardness and corrosion resistance of the alloy.

Inconel625 has excellent physical properties, with a density of about 8.44g/cm³, a melting point between 1290℃ and 1350℃, a thermal conductivity of 12.1W/m•℃ at 100℃, and a specific heat capacity of 430J/kg•℃. Its elastic modulus is 205GPa, shear modulus is 79GPa, and resistivity is 1.28μΩ•m. These physical properties enable Inconel625 to work stably in the temperature range of -200℃ to 980℃, and adapt to a variety of high-temperature application scenarios.
