ASTM A312 TP316L Stainless steel seamless pipe
Grade 316L is an austenitic stainless steel that can operate from 450 degrees Celsius to 850 degrees Celsius roughly. The range differs depending on the pressure of a system, the components flowing inside the pipe and the environment outside it. Marine environment is full of chloride ions and the wind and water are salty.
The salty conditions catalyze all forms of corrosions because they act as a medium for electron transfer for oxidation and reduction chemical reactions. The 316L stainless steel pipe has a lower carbon content than the ASTM A312 TP316 which means, there is less intergranular precipitation and local corrosion due to welding. Also, the material has molybdenum in addition to chromium and nickel which is specifically resistant to chloride ion stress corrosion.
