UNS S31700 stainless steel 317 is an austenitic chromium-nickel stainless steel, it's a modified version of 316 stainless steel, with excellent strength and corrosion resistance. The high Molybdenum content enhances the 317 grade's superior pitting resistance. It is the most corrosion resistant of the 300 Series alloys and possesses the highest tensile and creep strength properties at elevated temperatures.
