Steel Properties
AISI 316 is an austenitic stainless chromium-nickel-molybdenum steel. Due to the addition of 2 to 2.5% molybdenum, the corrosion resistance of AISI 316 compared to standard austenitic grades 1.4301 and 1.4307 is much better. AISI 316 is well suited for machining. Due to the molybdenum content AISI 316 has a good resistance in chloride-containing media and non-oxidizing acids.
