Product Introduction

317 stainless steel pipe has high molybdenum content and has excellent pitting resistance, especially in chloride environments. The tensile strength and creep strength and corrosion resistance of alloy 317 pipe are the highest in the 300 series. The outer diameter range of 317 SS pipe is 6-630mm, and the wall thickness range is 0.5-50mm. S31700 material can be used in high temperature environments up to 800℃ and is often used in ships, ship components, pulp and paper applications, and components in the oil and gas industry.
