Q: What is SPCC material?
A: SPCC is a grade of "general-purpose cold-rolled carbon steel sheet and strip" in the Japanese JIS G 3141 standard. S = Steel, P = Plate, C = Cold-rolled, C = Commercial grade.
Q: Which standards does SPCC comply with?
A: It primarily complies with JIS G 3141; in China, it corresponds to Baosteel Q/BQB 402 and the national standard GB/T 11253.
Q: What is the difference between SPCC, SPCD, and SPCE?
A: SPCC = Commercial grade; SPCD = Stamping grade; SPCE = Deep drawing grade, with formability increasing in that order.
Q: What are the heat treatment options for SPCC?
A: A = Annealed; S = Annealed + Leveled; 8 = 1/8 Hard; 4 = 1/4 Hard; 2 = 1/2 Hard; 1 = Hard.
Q: How to indicate SPCC that guarantees tensile test values?
A: Add "T" after the grade, i.e., SPCCT.
