SPCC cold rolled steel coil adds more good dimensional properties than SPHC Steels. Also, after the cold rolling process there are some additive processes like rewinding, annealing, and then skin passing to make a complete SPCC material with bright finish.
Chemical Composition of SPCC cold rolled steel coil
| Grade | C | Mn | P | S | Alta |
| DC01, SPCC | ≤0.12 | ≤0.60 | ≤0.045 | ≤0.045 | ≥0.020 |
| DC02, SPCD | ≤0.10 | ≤0.45 | ≤0.035 | ≤0.035 | ≥0.020 |
| DC03, SPCE | ≤0.08 | ≤0.40 | ≤0.030 | ≤0.030 | ≥0.020 |
| DC04, SPCF | ≤0.06 | ≤0.35 | ≤0.025 | ≤0.025 | ≥0.015 |
Dimensional Characteristics of SPCC Steels:
The applicable thickness for this SPCC cold rolled steel coil as defined in the JIS 3141 starts from 0.25 mm to 2.5 mm or over. However the width of SPCC material ranges to 2000 mm.
Product Advantages
1.The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.
2.It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide, etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.
