Product Introduction

ASTM A269 TP316 tube is composed of 16% chromium, 10% nickel, and 2% molybdenum. SS316 is more corrosion resistant than 304 material and can be used in high pressure and high temperature as well as low pressure and low temperature applications. S31600 also has excellent oxidation resistance. ASME SA269 Gr 316 tubes are widely used in various pressure vessel grades. We htpipe manufacturers supply 1.4401 AISI 316 seamless and welded pipes in many types. Contact us for more information and free quotes!

316 SS Tubing Pressure Rating

According to ASTM A269, the pressure rating of stainless steel 316 tubing is usually based on its wall thickness and outside diameter (OD). The thicker the wall, the smaller the outer diameter, the higher the pressure rating.
