Cold Rolled Steel Grades Equivalent Chart

Cold rolled steel grades are named differently in every market: a European drawing says DC04, a Japanese die shop says SPCE, an American order says DDS, a Russian contract says 08ю, an Indian tender says CR3. This chart cross-references the five common quality levels across EN 10130, DIN 1623, JIS G3141, ASTM A1008, GOST 9045, IS 513 and GB/T 5213 so buyers and engineers can specify the right coil the first time.

Cold Rolled Steel Grade Equivalent Chart

Quality level	EN 10130 (Europe)	DIN 1623 (old German)	JIS G3141 (Japan)	ASTM A1008 (USA)	GOST 9045 (Russia/CIS)	IS 513 (India)	GB/T 5213 (China)	Typical use
Commercial quality (CQ)	DC01	St12	SPCC	CS Type A/B	08пс	CR1	DC01	Bending, tube, panels, galvanizing base
Drawing quality (DQ)	DC03	St13	SPCD	DS Type B	08пс ВГ	CR2	DC03	Moderate draws, wheels, cases
Deep drawing (DDQ)	DC04	St14	SPCE	DDS	08ю (08Yu)	CR3 / CR4	DC04	Sinks, housings, auto inner panels
Special deep drawing (SDDQ)	DC05	St15	SPCE / SPCF	DDS / EDDS	08ю ВОСВ	CR4	DC05	Severe multi-stage draws, auto panels
Extra deep drawing, IF steel (EDDS)	DC06	—	SPCF / SPCG	EDDS	01юТ	CR5	DC06	Most severe draws, exposed auto skins

Matches are commercial approximations. Chemistry limits and guaranteed r/n values differ slightly between standards — when a die trial or certification depends on it, specify mechanical minimums on the purchase order rather than relying on the grade name alone.

Mechanical Properties by DC Grade (EN 10130)

Grade	Yield ReL (MPa)	Tensile Rm (MPa)	A80 (%)	r90	n90
DC01	140–280	270–410	≥ 28	—	—
DC03	140–240	270–370	≥ 34	≥ 1.3	—
DC04	140–210	270–350	≥ 38	≥ 1.6	≥ 0.180
DC05	140–180	270–330	≥ 40	≥ 1.9	≥ 0.203
DC06	120–170	270–330	≥ 38	≥ 2.1	≥ 0.220

How to Choose the Right Grade

Bending, tube, panels, galvanizing base: DC01 / SPCC — lowest cost, widest availability.
Moderate draws: DC03 / SPCD — guaranteed r-value begins here.
Deep drawing: DC04 / SPCE / DDS — the standard DDQ choice.
Severe or multi-stage draws: DC05 — specify when DC04 fails the die trial.
Most extreme draws / exposed skins: DC06 (IF steel) — titanium-stabilised, highest formability.

Old DIN St12 / St13 / St14 Still on Your Drawings?

Many Middle East, African and Iranian buyers still order ST12, ST13 and ST14 from legacy German drawings. DIN 1623 was superseded by EN 10130: ST12 → DC01, ST13 → DC03, ST14 → DC04. We accept RFQs in either naming and confirm the EN grade on the mill test certificate.

FAQ

Is SPCC equal to DC01?

Commercially yes. Both are commercial-quality CRC; JIS allows slightly higher P/S. See the detailed SPCC vs DC01 comparison.

What is the ASTM equivalent of DC04?

DDS (Deep Drawing Steel) under ASTM A1008. For DC05-level performance, specify DDS with agreed r/n minimums or EDDS.

What is 08ю steel?

08ю (08Yu) is the aluminium-killed deep drawing grade under GOST 9045 used across Russia and the CIS — the working equivalent of DC04/DC05. We export it with EAC-market-friendly documentation.

Which grade for hot-dip galvanizing feed?

DC01/SPCC full hard is the common feed for continuous galvanizing lines with in-line annealing. See our hot rolled vs cold rolled for galvanizing guide.
