Stainless steel density refers to substance mass per unit volume, it is one of the typical properties of stainless steel, commonly, the density of stainless steel ranges from 7600 kg/m3 to 8000 kg/m3. Stainless steel is a widely used material, containing at least 10.5% of Chromium, and other elements added to form stainless steel structure, these elements have Carbon, Silicon, Manganese, Phosphorus, Sulfur, Nickel, Molybdenum, Titanium, and Copper, it is noted as high strength and excellent corrosion resistance. Different chemical compositions and content determine the difference in grades’ densities. 304 and 316 Stainless Steel are the most and the second used grades and their densities are not the same, thus when calculating stainless steel weight, it is different between 304 and 316 stainless steel.
Density of 304 Stainless Steel: 7930 kg / m3 | 0.286 lb/in3
The density of 304 stainless steel is 7.93 g/cm3 (grams per cubic centimeter), which translates to 7,930 kg/m3 (kilograms per cubic meter). The density of 304 stainless steel is slightly higher than ferritic and martensitic stainless steels (e.g., 403) and slightly lower than austenitic stainless steels (e.g., 316). 304 stainless steel is also slightly denser than iron, but lower than copper. In contrast, aluminum has the lowest density.
Density of 316 Stainless Steel: 7980 kg / m3 | 0.288 lb/in3
The density of 316 stainless steel is 7.98g/cm³, a little higher than 304 stainless steel.

Stainless Steel Density Conversion, kg/m3, g/cm3 and lbs/in3
The density of stainless steel is calculated by dividing the mass by the volume, usually measured in g/cm3, kg/m3, and lbs/in3, each unit can be converted to other units.
Conversion: 1 kg/m3 = 0.001 g/cm3 = 1000 g/m3 = 0.000036127292 lbs/in3.

Density Relations with Temperature and Pressure
Densities of stainless steel vary by changing either the temperature or the pressure, in general, increasing the temperature decreases the density, and increasing the pressure always increases the density.
How To Calculate The Density Of Stainless Steel?
To calculate the density of steel, you will need to know the mass of the steel and the volume it occupies. The density of steel is calculated by dividing the mass of the steel by its volume. Here is the formula for calculating the density of steel:
The density of steel = mass of steel/volume of steel
For example, if you have a piece of steel that has a mass of 15 kilograms and a volume of 2 cubic meters, the density of the steel would be:
Density of steel = 15 kg / 2 m3 = 7.5 kg/m3
Stainless Steel Weight Calculate
Stainless steel weight calculation depends on the density, the higher density the more weight, that is why 304 stainless steel material is a little lighter than 316 stainless steel under the same condition.
There are formulas for stainless steel tubular and flat products to calculate the weight, stainless steel forms have pipe, plate, bar and others.
