Q: What is SPCC?
A: SPCC stands for Steel Plate Cold Commercial, a Japanese JIS standard for cold-rolled carbon steel sheets and strips. It is low in carbon, has a smooth surface, and good formability. Unless otherwise specified, it is annealed + smoothed (S), with bright/matte finish options available.
Q: What do the suffixes in SPCC (e.g., SPCC-S-B) represent?
A: S = Annealed + smoothed; 1/8 hard (8), 1/4 hard (4), 1/2 hard (2), hard (1); B = bright finish, D = matte finish; T = tensile test value required (SPCCT).
Q: What are the common thicknesses of SPCC?
A: The mainstream thicknesses are 0.5/0.8/1.0/1.2/1.6/2.0/2.3/3.2mm. Cold-rolled standard thicknesses are ≤3.2mm, and thicker thicknesses are mostly SPHC hot-rolled.
Q: How do SPCC correspond to domestic grades? A: DC01 and Q195/Q215 cold-rolled sheets, similar to GB/T 11253, have similar composition and mechanical properties and can be substituted for each other according to customer standards.
Q: How are the density and theoretical weight of SPCC calculated?
A: Density 7.85 g/cm³; Theoretical weight (kg) = Thickness (mm) × Width (m) × Length (m) × 7.85.
