The density of stainless steels can vary depending on their types and components. However, generally, the density value for 304-grade stainless steel is approximately around 7.93 grams per cubic centimeter. This means that the density of 304-grade stainless steel is the mass of 7.93 grams in each cubic centimeter of a cube. Density is a measure that expresses the mass per unit volume of a material and is typically expressed in grams per cubic centimeter (g/cm³).
