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
What is the density of stainless steel?
For most grades, a guide range of 7.65-7.95 g/cm³, or 7650-7950 kg/m³, is used. The exact value depends on grade and chemical composition.
How much does 1 m³ of stainless steel weigh?
One cubic meter of stainless steel usually weighs about 7650-7950 kg. For engineering calculations, use the density of the specific grade.
Why does stainless steel density differ by grade?
Density is affected by chromium, nickel, molybdenum, carbon and other alloying elements. Austenitic, ferritic and other steels can therefore differ slightly in mass.
