ASTM A312 TP316 Marine Grade Stainless Steel Seamless Pipe Cold Drawn Pickled for Corrosion Resistance
ASTM A312 TP316 is a molybdenum-bearing austenitic stainless steel seamless pipe. The 2-3% molybdenum addition provides TP316 with superior resistance to pitting and crevice corrosion in chloride environments compared to 304 grade, while maintaining excellent toughness and weldability.
TP316 pipe is the standard choice for marine, chemical, and process service applications where media is more aggressive. It is supplied annealed and pickled with certified mill test reports for full traceability.
