NM400 steel weight calculator plate weldability

NM400 steel is weldable using conventional welding methods, but preheating is recommended to avoid cracking. The weight of an NM400 steel plate can be calculated using the formula:

Weight (kg) = Thickness (mm) * Width (m) * Length (m) * Density (kg/m³)

Where the density of NM400 steel is 7,850 kg/m³.
