A: It's a common cold-rolled low-carbon steel strip (generally used) conforming to the Japanese JIS G3141 standard, commercial grade, equivalent to Chinese national standards DC01, St12, and Q195.
A: Steel Plate Cold Commercial.
Q: Is SPCC cold-rolled or hot-rolled?
A: Cold-rolled, produced by cold-rolling hot-rolled pickled coils.
A: SPCC=Cold-rolled, good surface finish, high precision, good plasticity; SPHC=Hot-rolled, poor surface finish, low precision, cheaper price.
A: Soft material (annealed state), also available in hard states such as 1/2H and H (only guaranteeing hardness).
