What is SPCC Steel? What is the production process?

 SPCC steel is a commercial high quality cold rolled steel in Japanese standard JIS G 3141.

"S" means steel, "P" means plate, "C" means cold rolled, the second "C" means commercial use.
​As a basic carbon steel, SPCC can be classified as a mild steel, equivlent to Chinese steel grade Q195 and US steel grade SAE1006.
