The reason for choosing stainless steel is normally due to advantages given by physical properties such as corrosion resistance.
In addition to corrosion resistance, the advantageous physical properties of stainless steel include:
High and low temperature resistance
Ease of fabrication
High Strength
Aesthetic appeal
Hygiene and ease of cleaning
Long life cycle
Recyclable
Low magnetic permeability

Why Would You Want to Use 304, Then?
Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel. It contains high nickel content that is typically between 8 and 10.5 percent by weight and a high amount of chromium at approximately 18 to 20 percent by weight. Other major alloying elements include manganese, silicon, and carbon. The remainder of the chemical composition is primarily iron.
The high amounts of chromium and nickel give 304 stainless steel excellent corrosion resistance.
Common applications of 304 stainless steel include:
