Niobium and molybdenum are added to provide the required strength to Inconel UNS N06625 without the heat treatment, which is very important in extending mechanical strength. These 625 round bars have excellent pitting, crevice corrosion, stress-corrosion cracking, and oxidation resistance, and consequently are suitable in harsh service conditions that require high pressure and extreme temperatures.
USA Piping Solution is one of the top manufacturers and suppliers of Inconel 625 round bars in the USA, which offers the high-strength nickel-chromium-molybdenum alloy bars of high temperature and corrosive conditions. Our alloy 625 round bars and rods are manufactured in accordance with ASTM B446 / ASME SB 446 standards and are widely used in chemical processing, offshore, aerospace, and marine industries.
