What is the difference between 304 Stainless Steel and 316 Stainless Steel finish on fasteners?

The main difference between 304 stainless steel fasteners and 316 stainless steel fasteners is the level of corrosion resistance needed for your project. 304 stainless steel is best suited for applications where aesthetics matter and corrosion resistance is not highly required. 304 is more cost effective for applications where corrosion resistance is not the main concern. 316 stainless steel fasteners are used for their corrosion resistance properties in environments where chloride exposure is a high concern, such as marine environments or industrial settings with corrosive chemicals. 316 offers the highest level of corrosion resistant protection but sacrifices some aesthetic appeal, with its dull matte finish.
