JIS G3141 Cold-Rolled Steel Sheet Grade Guide: SPCC, SPCD, SPCE, SPCF, SPCG

JIS G3141 covers five cold-rolled steel sheet grades from SPCC (general) to SPCG (super deep drawing IF steel). Full comparison of composition, elongation, r-value, and ASTM/EN equivalents — with application decision table.

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.
