Material selection SS304 vs SS316
+++++
We are manufacturing packaging equipment and just sold a project to China, we would like to select the best Stainless Steel and wonder if we must used the SS316, we are trying to find a selection guide, the only information we have tell us that the SS316 would not perform better.
Humidity 95-98%
Tropical environment
Temperature can drop from 40 to 0 celcius during night
There is condensation on equipment and accumulation of corrosive dust on it.
Products: 1 line-Salt NaCl, 2 line Amonium Chloride Nh4Cl, 3 line light and heavy Soda Ash Na2COl

Neither 304 not 316 stainless will stand up to a chloride environment. Perhaps you should investigate duplex or super-duplex stainless steels (2205 or 2507) for these service conditions.

T316 will perform better than T304 in chloride, however neither may be entirely satisfactory. I'd suggest you look into duplex satinless alloys for this application.
