What is the elongation (plasticity) of SPCC?
A: For thicknesses t=0.25~2.5mm, ≥ 32~39%, less prone to cracking during cold bending/stamping.
What is the hardness of SPCC?
A: Annealed state (soft state):
HRB: 85~110
HV: 160~200
What is the density (specific gravity) of SPCC?
A: 7.85 g/cm³ (consistent with ordinary carbon steel).
What is the elastic modulus (Young's modulus) of SPCC?
A: Approximately 205 GPa (general value for carbon steel at room temperature).
What is the common thickness range of SPCC?
A: Cold-rolled sheet/coil: 0.3~3.2 mm. Commonly used: 0.5, 0.8, 1.0, 1.2, 1.5, 1.6, 2.0, 2.5, 3.0 mm.
