Overview
Inconel 625 is TOKO TECH's most popular nickel alloy pipe grade. Its nickel-chromium-molybdenum-niobium composition delivers exceptional resistance to pitting and crevice corrosion (PREN >45) combined with high strength at temperatures up to 980°C. Widely used in subsea umbilicals, chemical processing, and aerospace — wherever both strength and corrosion resistance are critical.
