SPCC Cold-Rolled Steel Sheet: JIS G3141 Explained — Properties, Surface Finish, and ASTM Equivalent

SPCC is Japan's general-purpose cold-rolled steel sheet under JIS G3141. No minimum tensile strength is specified — only elongation and chemical composition. Full guide with ASTM A1008 and EN 10130 DC01 equivalents, surface finish codes, and selection against SPCD/SPCE.

SPCE Deep-Drawing Cold-Rolled Steel: JIS G3141 Grade for Complex Stampings

SPCE is the deep-drawing grade in JIS G3141 cold-rolled steel — lower carbon and phosphorus than SPCC, with r-value ≥ 1.4 and elongation ≥ 42%. Use it when SPCC tears or thins excessively in deep draws. Full guide with ASTM DDS and EN DC04 equivalents.
