The Difference Between SPCC and SPCD

SPCC was originally the Japanese Standard (JIS) designation for "general purpose cold-rolled carbon steel sheet and strip." Now, many countries and companies use it directly to designate similar steels they produce. Note: Similar designations include SPCD (cold-rolled carbon steel sheet and strip for stamping), SPCE (cold-rolled carbon steel sheet and strip for deep drawing), SPCCK and SPCCCE (special steel for televisions), and SPCC4D and SPCC8D (hardened steel, used for bicycle rims, etc.), each used for different applications.

Common structural steel designations in Japanese steel (JIS series) consist of three main components: the first indicates the material, such as S (Steel) for steel and F (Ferrum) for iron; the second indicates the shape, type, and application, such as P (Plate) for plate, T (Tube) for tube, and K (Kogu) for tool; and the third indicates a characteristic number, generally representing the minimum tensile strength. For example: SS400-the first "S" stands for "Steel," the second "S" stands for "Structure," and the "400" represents the lower limit tensile strength of 400 MPa. Overall, it designates ordinary structural steel with a tensile strength of 400 MPa.

Supplement: SPCC-indicates general cold-rolled carbon steel sheet and strip, equivalent to China's Q195-215A grade. The third letter "C" stands for "Cold." If tensile testing is required, add "T" to the end of the grade to make it SPCCT.

A Japanese steel grade (JIS standard series) designating cold-rolled carbon steel sheet and strip for stamping, equivalent to China's 08AL (13237) high-quality carbon structural steel.

SPCD Nomenclature Explanation:

The first digit indicates the material; the "S" (Steel) designates the steel. The second code indicates the shape, type, and purpose. P (Plate) stands for plate.

SPCD's main uses:

For stamping and drawing applications, it's between SPCC and SPCE. For stamping applications without drawing, SPCC can be used, while for deep drawing, SPCE can be used.

For applications between the two, SPCD can be used.
