SPCC is the commercial-quality cold rolled steel grade under JIS G3141 — the most quoted CRC designation across Asia, the Middle East and Africa. It matches EN DC01 / old DIN St12 and is the default grade for bending, roll forming, tube making and as substrate for galvanizing.

SPCC Chemical Composition (JIS G3141)
| Element (max %) | SPCC |
|---|---|
| C | 0.15 |
| Mn | 0.60 |
| P | 0.100 |
| S | 0.050 |
SPCC Mechanical Properties
| Property | Requirement |
|---|---|
| Tensile strength Rm | ≥ 270 MPa |
| Elongation (0.6–1.0 mm) | ≥ 37% |
| Hardness (annealed, HRB) | ≤ 65 (typical) |
| Temper options | A (annealed), S (skin-passed), 1/8H–1H on request |
Values follow JIS G3141 for skin-passed sheet 0.7–2.0 mm. Thinner or full-hard material is quoted against the agreed specification; always confirm the governing standard edition on your purchase order.
International Equivalent Grades
| Standard | Closest equivalent |
|---|---|
| EN 10130 (Europe) | DC01 |
| DIN 1623 (old German) | St12 / ST12 |
| ASTM A1008 (USA) | CS Type B |
| GOST 9045 (Russia/CIS) | 08пс |
| IS 513 (India) | CR1 |
| GB/T 5213 (China) | DC01 |
Equivalents are approximate commercial matches, not certified substitutions. When your drawing or die trial depends on r-value and n-value, specify the mechanical requirements explicitly and we will match the correct grade. See the full cold rolled steel grades equivalent chart.
Typical Applications
- General fabrication and bending
- Welded pipe and tube (round/square)
- Panels, drums, shelving, furniture
- Substrate for hot-dip galvanizing lines
- Electro-galvanizing and painting base
How SPCC Compares to Neighbouring Grades
SPCC and DC01 are commercial twins; buyers used to Japanese-standard mills quote SPCC, European-standard buyers quote DC01. For drawing duty step up to SPCD (≈ DC03) or SPCE (≈ DC04/DC05). See our SPCC vs DC01 comparison for a detailed breakdown.

FAQ
What does SPCC stand for?
Steel Plate Cold-rolled Commercial — the JIS G3141 designation for commercial-quality cold rolled sheet and coil.
SPCC vs SPCC-SD — what is the difference?
SD indicates a skin-passed dull finish. SB is skin-passed bright. The base grade is the same; the suffix sets surface finish and temper condition.
Can SPCC full hard be supplied for galvanizing lines?
Yes — SPCC-1H/full hard coil (unannealed) is a common feed for continuous galvanizing lines that anneal in-line. State whether your line anneals before zinc pot entry.
What thickness tolerance do you hold?
Standard JIS tolerance; tighter ±0.02 mm available for precision users on request. Confirm tolerance class in the RFQ for accurate pricing.
