The difference between SECC and SECD

 Key words: SECD steel chemical property, SECD steel tensile strength, SECD steel yield strength, SECD steel Elongation, SECD deep drawing steel.

ASK : What’s the difference between SECC and SECD

ANSWER: Both SECC and SECD are Electro-galvanized steel grade. Compared with SECC, SECD have the better Elongation rate, it means SECD steel material have the better Plasticity and stamping performance. SECC is the general use quality material. However, SECD is the drawing quality material. The “D” in SECD means “ Drawing” The mechanical property of SECD is below:

Grade	Yield Strength MPa	Tensile strength MPa	Elongation % min
			0.4-≤0.6mm	0.6-≤1.0mm	1.0-≤1.6mm	1.6-≤2.3mm	2.3-≤2.5mm	2.5 or Over
SECD	-	270 min	36	38	39	40	40	41
