The difference between 321 and 304 Grade.
If we consider from chemical and alloy composition,there is only one obvious different between 304 and 321,that is the Titanum element,in 321 the Ti is added to strengthen materials resistance to climate,environment and changing on outside forcing,and the other difference is not obvious but still important,that is,it is owning extra 1% Nickle than 304 grade,in 321 the Nickle is 9% min,reference on ASTM,however in 304,it is 8% min.With more nickle content and adding of Titanium,321 governs more stability to resist on climate change and outside forcing etc.
