4. GB 40CrNiMoA Steel Weight Formula

◆ Bar: diameter * diameter * 0.00617 = kg/m (weight per meter)
kg/m X length (m) = KG (weight per piece)

◆ Plate: width * height * 0.00785 = kg/m (weight per meter)
Area (m²) x thickness (m) x density (g/cm³) = KG (weight per piece)

◆ Flat steel: weight per meter (kg) = 0.00785 × thickness × side width

◆ Pipe: weight per meter (kg) = 0.02466 × wall thickness × (outer diameter – wall thickness)
