Q: What are the elongation requirements for SPCC?
A: Annealed state (SPCC-S) elongation ≥ 34%, decreasing with increasing hardness; for example, 1/2 hard SPCC-2 is approximately 18–25%.
Q: What are the hardness grades and corresponding ranges for SPCC?
A: Classified by HRB/HV.
Q: What are the density and elastic modulus of SPCC?
A: Density ≈ 7.85 g/cm³, elastic modulus ≈ 205 GPa, consistent with ordinary carbon steel.
Q: What is the corresponding Chinese national standard (GB) grade for SPCC?
A: Approximately corresponding to GB/T 11253 Q195/Q215, but the feasibility of substitution needs to be verified based on specific performance parameters.
Q: What are the equivalent grades for SPCC in the EU (EN) and US (ASTM)?
A: EU EN DC01, US ASTM A1008/A1010, German DIN St12, and international ISO CR01 can be used for cross-standard material selection reference.
