316 stainless has 2% to 2.5% molybdenum compared to 304, which has about 0.5%. 316 has slightly more nickel and slightly less chromium than 304. The result of these slight differences in chemical composition is that 316 stain - 316 stainless generally costs 25%-35% more than 304. less ...
202 stainless seems to be a relatively new composition for many applications which have traditionally used 304 stainless steel. I think there is little doubt that 304 is "better" thanks to its higher nickel content, but more expensive for the same reason. BPA is related to plastics ...

Better passivation characteristics shown by the rolled material were attributed to thicker passive film with a higher Cr:Fe ratio, the higher Cr being the result of enhanced diffusion through the oriented grains in the rolled material. Introduction Type 304 stainless steel is the general purpose ...
