Q: What is the material of DC01 coil?
A: It is a low-carbon cold-rolled steel coil under the DIN EN 10130 standard, originally designated St12/FeP01. It belongs to the general-purpose cold-forming basic steel grade, with a carbon content ≤0.12%.
Q: What are the applicable standards for DC01?
A: The core standard is DIN EN 10130, corresponding to Chinese GB/T 5213, Japanese JIS G3141 (SPCC), and American ASTM A1008, etc.
Q: What is the difference between DC01 and SPCC?
A: Both are low-carbon cold-rolled steels. DC01 follows the EN standard, while SPCC follows the JIS standard. Their composition and properties are similar; the main differences lie in the standard system and tolerances for some indicators.
Q: What is the production process for DC01 coil?
A: Hot-rolled coil → pickling → cold rolling → continuous annealing → leveling → slitting/finishing. Annealing eliminates work hardening and restores plasticity.
Q: What are the supply conditions for DC01?
A: Primarily cold-rolled annealed (CRCA) condition, with a surface typically passivated or unpassivated. Smooth, matte/polished finishes are available upon request.
