A312 TP317 is a T300 series austenitic stainless steel pipe. The composition of chromium-nickel austenitic alloy is similar to A312 TP317L stainless steel pipe, but the molybdenum content is lower.
A312 TP317 Welded Stainless Steel Pipe has a higher balance of Chromium, Nickel and Molybdenum which helps in improving corrosion resistance as up to 30% Chromium content has anti-sensitization properties during welding and heat treatment. Hence A312 TP317 Welded Round Pipe can be used in the Oil or Gas Industry.
