Inconel Alloy ASTM B444 625 Small Diameter Steel Tube

Inconel 625 (ASTM B444) small diameter steel pipe is a high-performance pipe based on nickel-chromium alloy (Ni-Cr), which is strengthened by adding molybdenum (Mo) and niobium (Nb). It has excellent corrosion resistance, high temperature strength and oxidation resistance. The material performs well in acidic, seawater and chloride environments, especially resistant to pitting, crevice corrosion and stress corrosion cracking, and is suitable for marine engineering, chemical industry, aerospace and energy fields. Its small diameter design is suitable for precision fluid transportation, heat exchangers and high-pressure pipeline systems. It maintains structural stability at extreme temperatures from -200°C to 980°C, and has good weldability and processability. It is the preferred material for high reliability under harsh working conditions.
