316(Cr-Ni-Mo)

1. Introduce – 316 stainless steel is formulated to have improved corrosion resistance over 300 series and lower stainless steels – Increased corrosion resistance and high temperature strength over grade 304 by adding approximately 2-3% Mo – UNS S31600 * 316 vs 304 : Both 304 and 316 contain Cr, an element that improves corrosion resistance Characteristics316304Alloying elements (Mo)Added(Approx. 2~3%Mo)→ Better corrosion resistance than 304 due to Mo additionNot AddedPREN value23~28→ Mo : Role in improving PREN value 3.3 times compared to Cr18~20 * PREN (Pitting Resistance E...
