The SS 317 is a bit different from SS 317 L. The stainless steel 317 has chromium content in 4-30 percentages. Apart from austenitic, SS 317 is classified into ferritic and martensitic steel as well due to its crystalline structure. Moreover, it is an advanced version of SS 316. This advanced version has corrosion resistance and high strength.

The use of this grade steel gives good resistant and strength to the pipes and tubes. Therefore, the pipes and tubes are resistant towards sensitization as well. This makes the welding and thermal processes easier. Under the annealed condition, the pipes and tubes display their non-magnetic property. However, they show a slight magnetic property because of welding.

When it comes to corrosion, the pipes and tubes can resist chemical attacks that occur in pulp and paper industries this is due to the increased quantity of molybdenum, chromium, and nickel in SS. They can resist sulfuric acidic concentrations at 120 degrees F temperature. Even if the acid is present in 5 percent concentration then also the pipes and tubes made of SS317L can resist the corrosion. To ensure their performance under operating conditions, service tests are done on pipes and tubes in our testing unit.
