SPCF steel are different with SPCE steels in a way that mechanical properties of SPCE steel change little with its age unlike the SPCE steel. SPCF steels are deep drawing quality non aging cold rolled steels, which are consumed for drawing applications.
SPCF Steel Dimensional Characteristics : The appropriate thickness for this SPCF material as demarcated in the JIS G 3141 initiates from 0.25 mm to 2.5 mm. The width of SPCF steel ranges from 950 mm to 2000 mm.
SPCF Steel Chemical Composition :
Maximum percentage of Carbon (C) is 0.08 percent.
Maximum percentage of Manganese (Mn) is 0.45 percent.
Maximum percentage of Phosphorous (P) is 0.020 percent.
Maximum percentage of Sulphur (S) is 0.030 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
SPCF Steel Mechanical Properties :
The tensile strength of the SPCF Steels is expressed in Newton per millimeters and it must be at-least 270 N/mm2 (MPa) & the yield strength is 210 N/mm2 (MPa).
The minimum percentage ranges for elongation is from 40 to 45 percent starting from 0.4 mm to 2.5 mm and over.
