ASTM B163 Inconel 718 Pipe

Description:

ASTM B163 Alloy 718 seamless pipe is the preferred material for extremely high temperature, high pressure and corrosive environments, especially for aerospace, deep-sea oil and gas and nuclear power. Its ultra-high strength and corrosion resistance far exceed conventional stainless steel, but the cost is high. When selecting, it is necessary to comprehensively evaluate the working conditions (temperature, medium, life cycle cost). In severe acidic or ultra-high temperature scenarios, it is recommended to conduct corrosion tests or consult a material engineer.
