Because SPCC Simple directional cold rolling Sheet has not been annealed, its hardness is very high (HRB is greater than 90), and its machinability is extremely poor, so SPCC Simple directional cold rolling Sheet can only perform simple directional bending less than 90 degrees (perpendicular to the coiling direction). To put it simply, cold rolling is processed and rolled on the basis of hot rolled coils. Generally speaking, SPCC Simple directional cold rolling Sheet is a process of hot rolling—pickling—cold rolling.
Grade | Yield Strength | tensile strength | Elongation |
SPCC | ≤240 | ≥270 | ≥28 |
Remaining is iron (Fe) percentage and with few negligible impurities.
Mechanical Properties of SPCC Simple directional cold rolling Sheet:
Following are some of the mechanical properties of SPCC steels:
The tensile strength of the SPCC Steels is expressed in Newton per millimeters and it must be at-least 270 N/mm2 (MPa).
The elongation property of SPCC steel varies with the ranges of thickness.
The minimum percentage ranges for elongation is from 27 to 31 percent starting from 0.25 mm to 2.5 mm and over.
The weld ability of these materials is conformed.
