Cold rolled coils & sheets · Size & tolerance table

Cold rolled steel grade equivalents (EN 10130, ASTM A1008, JIS G3141, IS 513)

Standard: EN 10130 · ASTM A1008/A1008M · JIS G3141 · IS 513 (Part 1) formerly DIN 1623-1, ASTM A366 / A619 / A620

Cold rolled low-carbon steels for forming are graded by how much forming they can take, from commercial quality to extra-deep drawing. The table lines up the grade names of the main standards; the steels are close but not identical, because the standards set different limits and test pieces — specify one standard on an order rather than “DC01 or equivalent”.

Notes

ASTM A1008 replaced the separate specifications A366 (commercial), A619 (drawing), A620 (drawing, special killed) and A611 (structural) in 2000.
IS 513 (Part 1) now uses the designations CR1 to CR5; the old Indian grades O, D, DD and EDD correspond to CR1 to CR4.
