Type 316 is a molybdenum steel possessing improved resistance to pitting by solutions containing chlorides and other halides. In addition, it provides excellent elevated temperature tensile, creep and stress-rupture strengths.

Type 316 is more resistant to atmospheric and other mild environments than Type 304. it is resistant to dilute solutions (i.e. 1-5%) of sulfuric acid up to 120°F. However, in certain oxidizing acids, Type 316 is less resistant than Type 304. 316 is susceptible to carbide precipitation when exposed in the temperature range of 800° - 1500°F and therefore is susceptible to intergranular corrosion in the as-welded condition. Annealing after welding will restore corrosion resistance.
