The brand SPCC is derived from JIS, which is the abbreviation of Japanese Industrial Standards, that is, "Japanese Industrial Standards."
SPCC is included in JIS G 3141. The name of this standard number is "Cold-rolled Carbon Steel Plate and Steel Strip", which includes five grades: SPCC, SPCD, SPCE, SPCF, SPCG, etc., which are suitable for different application requirements. .

Different tempering degrees of SPCC
We often say that a grade cannot exist alone. Standard number + grade + suffix 1 + suffix 2 +... is a complete description. This principle is also common to SPCC. Different suffixes in the JIS standard represent different products, the most important of which is the tempering code. The meaning of the modulation degree code is as follows:
A--annealing only
S-standard tempering degree
8-1/8 Hard
4-1/4 hard
2-1/2 hard
1-Hard
What does annealing only and standard modulation mean? The standard tempering degree here usually refers to the annealing + flattening process. If it's not flat, it's just annealing. However, since the annealing process of steel plants is now equipped with a smoothing machine, and if it is uneven, the plate shape cannot be guaranteed, so uneven products are rarely seen now, that is, products like SPCCA are rare.
