What is SECC?
SECC is a stamping material, which is coated with a zinc layer on the surface of the cold-rolled sheet. Rust and corrosion-resistant. The price is relatively high. The general board thickness is 0.4~3.2mm.
Applicable grades of Japanese electro-galvanized steel sheet: SECC (original plate SPCC), SECD (original plate SPCD), SECE (original plate SPCE) Zinc layer code: E8, E16, E24, E32 Symbol: S-steel (Steel), E-plating (Electrodeposition) ), C-cold rolled (Cold), the fourth C-common grade (common).
SECC Material Specification
| Element code | C | Si | Mn | P | S |
| Content(%） | <0.12 | <0.05 | <0.50 | <0.025 | <0.025 |
The content of other residual elements in steel should meet the following requirements:
Cu<0.15%, Ni<0.15%, Cr<0.15%, As<0.05%, Sn<0.05%.
