Q: What is the full name of SPCC? What is the corresponding standard?
A: SPCC is the abbreviation for "Cold-rolled Carbon Steel Sheet and Strip" in the Japanese Industrial Standard (JIS G 3141). S = Steel, P = Plate, C = Cold, and C = Commercial.
Q: What are the core material properties of SPCC?
A: It is a low-carbon cold-rolled steel with a carbon content typically between 0.05% and 0.12%. It has good plasticity, medium stamping formability, uniform surface quality, and high cost-effectiveness. It is a representative general-purpose cold-rolled coil.
Q: Which grade in the Chinese national standard is SPCC equivalent to?
A: It is equivalent to DC01 in China's GB/T 11253. The chemical composition, mechanical properties, and applications of the two are essentially the same, and they are interchangeable.
Q: What are the common surface condition grades of SPCC?
A: There are two main types: ① Grade D (Matte): The surface has uniform pitting, a moderate coefficient of friction, and is suitable for stamping. ② Grade B (Bright): The surface is smooth and glossy, and is used in applications where appearance is a priority.
Q: What are the delivery conditions for SPCC?
A: It is usually delivered in the "annealed" state to ensure good plasticity. Some can be delivered in the cold-rolled hard state (unannealed) upon request, but this must be confirmed with the manufacturer in advance.
