Applicable grades: SPCC, SPCD, SPCE Symbol: S-steel, Plate, C-Cold, C-common, D-Draw, , E-deep leveling (Elongation).
SPCC is an abbreviation for cold rolled sheet, Steel Plate Cold rolled Commercial.
SPCD-deep drawing cold-rolled material, that stamping with cold-rolled carbon steel sheet and strip, the equivalent of China 08AL (GB / T13237-1991) quality carbon structural steel.
SPCE – ultra-deep drawing cold-rolled material, said deep drawing with cold-rolled carbon steel sheet and strip, the equivalent of China SC1 (GB5213-2001) deep-drawing steel.
SPCEN – To ensure non-timeliness, add N to SPCEN at the end of the grade.
