Cold-rolled carbon steel plates
SPCC: Generally uses cold-rolled plates, the same as Q195 and DC01 materials.
SPCD: Stamping grade, corresponding to DC03/04, with excellent deep-stamping performance.
SPCE: Ultra-deep-stamping grade, corresponding to DC05/06, with high surface quality.
Cold-rolled low-carbon steel plates (DC series)
DC01: General use, corresponding to SPCC.
DC03/04: For stamping/deep-stamping, corresponding to SPCD.
DC05/06: For ultra-deep-stamping/extra-deep-stamping, corresponding to SPCE.
