UNS s31600 stainless steel round bar is an austenitic chromium-nickel stainless steel containing molybdenum. This increases corrosion resistance, improves resistance to pitting chloride ion solutions and provides increased strength at elevated temperatures.
Properties of UNS s31600 are similar to those of type 304 except that type 316 is somewhat stronger at elevated temperatures. Corrosion resistance is highly improved. Particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids, acid sulfates and alkaline chlorides.
