Stainless steel 304 and 316

There are some customers telling us they need stainless steel items, but have no idea about the difference between stainless steel 304 and 316. We would like to give a briefly explanation:

1. SS316 is more expensive than SS304

2. SS316 is better than SS304 in corrosion resistance, so if the application areas are bad, like near sea, we highly recommend you choose SS316.

3. Chemical Composition:
