Specific Weight of Stainless Steel: Weight of 1 m³, Density and Reference Table
Stainless steel is an alloy steel that is resistant to corrosion in atmospheric and aggressive environments. Thanks to its chromium content and other alloying elements, it offers excellent corrosion resistance and is widely used in construction, mechanical engineering, the chemical industry, food processing and medical equipment.
Stainless steels are generally divided into three main groups: corrosion-resistant, heat-resistant and heat-strength steels. Each group is designed for specific operating conditions.
Corrosion-resistant grades are used where high resistance to moisture, chemicals and atmospheric corrosion is required. Heat-resistant grades are intended for elevated temperatures and aggressive gaseous environments. Heat-strength grades are designed for components subjected to significant mechanical loads at high temperatures.
When working with stainless steel, it is important to consider its physical properties. One of the key characteristics is density, which makes it possible to determine the weight of a required volume of material.
Stainless Steel Density Table
Although many users search for the “specific weight of stainless steel”, engineering calculations are usually based on the material’s density.
Specific Weight and Weight of 1 m³ of Stainless Steel
| Material | Density (g/cm³) | Weight of 1 m³ (kg) |
|---|---|---|
| Stainless steel | 7.65–7.95 | 7650–7950 |
The exact value depends on the stainless steel grade and its chemical composition.
Specific Weight Calculation
Specific weight is calculated using:
γ = ρ × g
where γ is the specific weight, ρ is density, and g is the gravitational acceleration (9.81 m/s²).
In practical engineering, density expressed in kg/m³ is used much more frequently than specific weight.
Density of Stainless Steel
Density is the mass contained in one cubic meter of material. It depends on the steel grade, chemical composition and temperature.
For most stainless steel grades, density ranges from 7650 to 7950 kg/m³, although certain special alloys may differ slightly.
Conclusion
The average density of stainless steel is approximately 7.65–7.95 g/cm³, corresponding to a weight of 7650–7950 kg per cubic meter. For accurate engineering calculations, always use the technical specifications for the specific stainless steel grade.
Frequently Asked Questions
Can the density of stainless steel be used for precise calculations?
The density and weight values for stainless steel in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of stainless steel differ from the table?
The actual weight of stainless steel depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of stainless steel from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of stainless steel is given in kg/m³ and the volume is in m³, the result will be in kilograms.
