Product information for purchasing teams
SS 316 adds 2 to 3% molybdenum to the 18/8 base. Molybdenum raises resistance to pitting and crevice corrosion in chlorides, so 316 is the usual choice for marine air, brine, chemical process and pharmaceutical service where 304 would pit.

Questions buyers ask
Should I choose 304 or 316?
If the material will see chlorides, such as sea air, brine, bleach or many process chemicals, 316 is the safer choice because of its molybdenum. For dry indoor, food or fresh-water service, 304 is usually enough and costs less.
What are the equivalent grades of SS 316?
SS 316 is UNS S31600, Werkstoff 1.4401, EN X5CrNiMo17-12-2 and JIS SUS 316.
