Frequently Asked Questions
How to calculate steel weight?
+
Steel weight is calculated using the formula: Weight = Volume × Density. The volume depends on the shape of the steel (plate, bar, tube, etc.), and the density varies by material type (mild steel, stainless steel, aluminum, etc.).
What’s the density of stainless steel?
+
The density of stainless steel varies by type. For example:
- Stainless Steel 304: 7,930 kg/m³ (0.286 lb/in³)
- Stainless Steel 316: 8,000 kg/m³ (0.289 lb/in³)
Why does weight vary by shape?
+
Weight varies by shape because different shapes have different volume calculations. For example:
- Plate: Length × Width × Thickness
- Round Bar: π × (Diameter/2)² × Length
- Pipe: π × (Outer Diameter² – Inner Diameter²)/4 × Length
