Stainless Steel 316L Pipe is made up of an austenitic stainless steel that has chromium, nickel and molybdenum in its composition with low carbon content than the 316 grade. The low carbon content of the pipes makes it easier for welding applications. The Stainless Steel TP316L Stainless Steel Seamless Pipe is used in aqueous applications where chloride ion corrosion is high. The material has low corrosion rates in chloride ion rich environment because of the molybdenum content in it. There are welded, seamless and fabricated pipes.

Corrosion Resistance:

Better resistant in many atmospheric environments and various corrosive media compared to grade 304.
Resistant to stress corrosion cracking above about 122°F (50°C).
Good resistant to pitting and crevice corrosion in warm chloride environments.
Corrosion resistance to potable water at ambient temperature range is up to 1000mg/L of chlorides. This reduces to about 500mg/L at 140°F.
316 / 316L is commonly known as “marine grade stainless steel”, although it is not resistant to warm sea water.

Heat Resistance:

Exceptional oxidation resistance in continuous service to 1700°F (925°C) and in intermittent service to 1600°F (870°C)
Fair resistance to carbide precipitation.
