Weight & Density of Stainless Steel 304 in g/cm3, kg/m3, lb/in3

Weight and Density of Stainless Steel 304 in g/cm3, kg/m3, lb/in3

The density of stainless steel 304 is 7,930 kg/m3, 7.93 g/cm3 (0.286 lb/in3). The weight of 304 stainless steel is 7,930 kg per cubic meter.

Density (ρ) is equal to the mass (m) of the object divided by the volume (V). The formula is ρ=m/V. The unit of density in the International System of Units (SI) is grams per cubic centimeter (g/cm3), grams per cubic decimeter (kg/dm3), or kilograms per cubic meter (kg/m3).

Why do you need to know the density of stainless steel?

You can calculate the weight of stainless steel according to its density and volume, for example

  • Metal manufacturers can calculate the weight of the metal to be melted based on the volume of the mold and the density of the metal before casting.
  • The weight of steel wire, steel plate, steel pipe, section steel and other stainless steel products can be calculated according to the density.
