Stainless Steel, AusteniticS31700 (317) Sheet & Plate

A modified version of Type 316 stainless steel with high strength and corrosion resistance.

Type 317 is an austenitic chromium-nickel stainless steel with excellent corrosion resistance; Its high Molybdenum content enhances the grade's superior pitting resistance. It was designed to be a higher strength alternative to the 316 grades.

Composed of larger amounts of chromium, nickel and molybdenum, alloy 317 also is more corrosion resistant compared to 316, and tougher than Type 304. This is the due to the high percentage of iron in its composition, which is much higher than many stainless steels.

This combination of iron with the chromium-nickel-molybdenum content yields a strong alloy.
