Seamless TP317LMn Stainless Steel Pipe

TP317LMn Seamless Stainless Steel Pipe is a high-performance, low-carbon, austenitic stainless steel pipe with increased levels of Molybdenum (Mo) and Nitrogen (N). This composition enhances its corrosion resistance and mechanical strength, particularly when compared to standard grades like 316L and 317L.
It is typically manufactured to specifications such as ASTM A312/ASME SA312 for seamless pipe intended for high-temperature and general corrosive service, with the grade designation TP317LMn or UNS S31726.
