What is the meaning of the SPCC coil designation?
A: Originating from the Japanese JIS standard, S stands for Steel, P for Plate, C for Cold, and the last C for Common. Overall, it refers to general-purpose cold-rolled carbon steel sheets and strips.
What are the approximate domestic and international grades for SPCC coils?
A: Domestically, it's similar to Q195-Q215A; in Germany, it corresponds to ST12; in the US standard, it's similar to 1008 or 1010; and in the European standard, it corresponds to DC01.
What are the implementation standards for SPCC coils?
A: The core standard is Japanese JIS G 3141. Some domestic steel mills, such as Baosteel, specify SPCC products in their enterprise standards such as Q/BQB402.
What is the general production process for SPCC coils?
A: Generally, ordinary carbon hot-rolled steel strip is used as raw material. After pickling to remove the oxide scale, it is cold-rolled at room temperature. Some products will also undergo subsequent processes such as annealing and leveling before being delivered in coils.
What is the thickness range of SPCC coils?
A: The thickness is usually less than 4mm, and the thinnest can be rolled to about 0.18mm, which can meet the needs of thin sheet materials in different applications.
