Dipti Metal Industries — Mumbai, India
📊 Overview
ASTM A1014 covers precipitation-hardening bolting (UNS N07718) for high-temperature service, typically produced from ASTM B637 bars/forgings. Inconel 718 fasteners offer very high tensile and creep-rupture strength up to around 700 °C with good corrosion resistance and weldability — ideal for turbines, valves, flanges, downhole and process duty.
