Stainless Steel 316 Pipe

ASTM specified sa312 tp316 pipe is meant for use in applications involving high temperature along with use in general corrosive media containing environments. Coming only second to austenitic grade 304, Stainless Steel 316 Pipe in terms of popularity and use, grade 316 is an alloy which can be used in more severe conditions. In fact, the popularity of stainless steel 316 seamless pipe surpasses stainless steel grade 310 due to its ability to effectively resist chloride ion stress related corrosion in comparison to other stainless steel grades.

Often referred to as marine grade, the pipes produced from stainless steel astm a312 tp316 can resist corrosion from sea water and brine solutions. In fact, the stainless steel pipe 1.4401 is often utilized in process streams which contain halides like chlorides, due to its ability to withstand the said compound. The addition of molybdenum in the alloy of Stainless Steel 316 Pipe not only improves resistance against chloride pitting, but also general corrosion. Alloy 316 food grade stainless steel pipes characteristically exhibits higher creep, stress to rupture as well as higher tensile strength properties even in elevated temperature settings. Similar to alloy grade 304, a shared trait between the former i.e. stainless steel 304 and astm a312 tp316 ERW is that they both can form a passivated oxide layer on the surface of pipes in oxidative condition. Thereby preventing the ss 316 erw pipes from being susceptible to corrosion against atmospheric oxidation.
