Weight and Density of 304, 316, 304L and 316L Stainless Steel
The density of stainless steel is about 7.93 g/cm3 (0.286 lb/in3). The weight of stainless steel per cubic inch is 0.286 pounds, and per cubic foot is 495 pounds.
Density, also known as specific mass or specific gravity, is a measurement of the mass in a specific volume. Density (ρ) is equal to the mass (M) of an object divided by the volume (V), the formula is ρ =m/V . The international density unit is kg/cm3, kg/dm3, kg/m3.
Specific Gravity and Density Table
The following table lists the specific gravity (gravity) and density of stainless steel 304, 316, 303, 304L, 316L and other AISI type stainless.
Observation:
- 1g/cm3 = 1kg/dm3
- The specific weight value in the following table is equal to the density value (g/cm3, metric).
