SPCC (JIS G3141, Japan) and DC01 (EN 10130, Europe) are the most common commercial quality cold-rolled carbon steels. They are produced by cold rolling hot-rolled coils (like SPHC) followed by annealing and skin-passing. This process provides superior surface finish, tighter dimensional tolerances, and excellent formability. They are widely used in automotive parts, home appliances, electrical components, and general sheet metal fabrication.
Chemical Composition
Typical chemical composition (% by mass) per JIS G3141 / EN 10130.
| Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) |
|---|---|---|---|---|---|
| SPCC / DC01 | ≤0.12 | ≤0.03 | ≤0.60 | ≤0.045 | ≤0.045 |
Note: SPCC/DC01 are commercial quality grades. DC01 is generally limited to C ≤ 0.12%, while SPCC allows slightly higher limits depending on the sub-grade (e.g., SPCC-SD for deep drawing).
Mechanical Properties
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Surface Finish |
|---|---|---|---|---|
