Also, it resists nitric and mildly acidic solutions.

Alloy information to know-
Alloy SS 317 is austenitic nickel and chromium SS that is having corrosion resistance ability. The high molybdenum content is improving the alloy excellent pitting resistance properties. It is the high corrosion resistant of series 300 and possesses the creep strength and high tensile strength properties at very high temperature.

Alloy SS 317L is low carbon austenitic nickel and chromium stainless steel that is used in the applications wherein annealing is not at all possible after welding and also corrosion resistant is required. The alloy is giving very good oxidation resistance at the intermittent service to 1600 Deg F and in continuous services to 1700 Deg F.
