DX51D is defined by EN 10346 (Continuously hot-dip coated steel flat products for cold forming), with the official European material number 1.0917 (EN 10027-2 system). It uses cold-rolled DC01 base steel, commercial quality (CQ) for general cold forming, hot-dip zinc coating (+Z), and is the most widely exported galvanized grade (62% global share, 2025 European Steel Association data).

DX51D The designation breakdown:

D: Cold-forming steel

X: Unspecified rolling state (cold-rolled DC01 base)

51: Commercial quality (general forming)

D: Hot-dip galvanized coating

Data source: EN 10346:2015, ASTM A653-24, JIS G3302:2021, GB/T 2518-2019, Gnee Steel 2025 Global Equivalent Manual

DX51D steel is highly ductile and flexible. It is used in complex dep-draught components and conforms to the BS EN 10346:2015 standard.

Classification: Ductile and flexible structural steel.

Product: Continuous hot-dip coated steel.

1. DX51D (1.0917) vs ASTM A653 CS Type B

Full interchangeable: CS Type B is the exact US equivalent, with identical yield (140–300 MPa), tensile (270–500 MPa), elongation (≥22%), and 180° bend performance.

Coating: ASTM G60/G90 corresponds to DX51D Z120/Z275; 95% of North American buyers substitute DX51D with ASTM A653 CS Type B for local supply.

2. DX51D vs JIS G3302 SGCC

98% property match: SGCC is the most common Asian equivalent, used across Japan, South Korea, Southeast Asia, and Australia.

Difference: SGCC allows slightly higher Si (≤0.05% vs DX51D ≤0.03%), but no impact on general forming and coating; 72% of global traders use SGCC as a direct DX51D replacement (2025 steel trade survey).

3. DX51D vs GB/T 2518 DC51D

Functional equivalent (not full interchangeable for EU/export): DC51D uses hot-rolled DD11 base (DX51D uses cold-rolled DC01), elongation ≥20% (DX51D ≥22%), bend mandrel 1.5t (DX51D 1t).

Suitable for domestic Chinese projects; not acceptable for EU certification or complex deep-drawing export parts.

4. Base Steel Equivalent (Uncoated)

DX51D’s cold-rolled base is DC01 (EN 10130, material number 1.0330), equivalent to SPCC (JIS G3141), CR1 (VDA 239-100), and Q195 (GB/T 700).

1. What is the official material number for DX51D?

The only official European material number is 1.0917 (EN 10027-2); 1.0226 is an outdated reference and not valid for current EN 10346:2015.

2. Can I use SGCC (JIS) instead of DX51D for EU projects?

No. SGCC does not meet EN 10346 certification; only DX51D (1.0917) or ASTM A653 CS Type B with EU test reports is acceptable for EU market projects.

3. Is DC51D a full equivalent to DX51D?

No. DC51D is a domestic Chinese equivalent for general use, but fails DX51D’s strict forming and surface standards for export, automotive, or high-precision applications.

4. What is the coating equivalent for DX51D Z275?

DX51D Z275 (275 g/m² zinc) = ASTM A653 G90 (0.90 oz/ft²) = JIS SGCC Z27, the standard heavy-duty corrosion-resistant coating for coastal/industrial environments.

5. Are there high-formability equivalents to DX51D?

For deeper drawing, use DX52D (1.0918) / ASTM A653 DQ Type B / JIS SGCD – these are the higher-formability equivalents in the same series.

DX51D (material number 1.0917) has c

lear, standardized equivalents across ASTM, JIS, GB, and other global systems-critical for cross-border material sourcing, certification, and cost optimization. Whether you need to substitute DX51D with SGCC for Asian markets, ASTM CS Type B for North America, or verify DC51D for domestic use, precise grade matching ensures compliance and performance.
