DX51D equivalent grades: ASTM, EN, JIS, GB, DIN
DX51D is hot-dip coated low-carbon steel for bending and profiling specified in EN 10346. The cross-reference runs across 6 standard systems and grades every candidate, so the reason a substitution is safe is on the same row as the name. The full DX51D data sheet carries the composition and mechanical tables.

Where a drawing says DX51D, DX51D+Z, IS 277 Grade O, SGCC satisfies it as written, with no concession needed. CS Type B (A653), DX52D, 08kp / 08ps galvanized differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. S250GD, DC01 serve the same purpose without being the same steel, so a substitution there needs the design re-checked rather than the certificate. The cross-reference below covers 1 in GB/T (China), 1 in IS (India), 1 in JIS (Japan), 1 in ASTM / ASME, 3 in EN (European), 1 in GOST (Russia/CIS).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| DX51D+Z | GB/T (China) | Identical | GB/T 2518 adopted the EN designation DX51D+Z. |
| IS 277 Grade O | IS (India) | Identical | IS 277 galvanized sheet, ordinary (O) grade. |
| SGCC | JIS (Japan) | Identical | JIS G3302 SGCC: commercial galvanized, Rm ≥ 270 MPa, no yield minimum; coating Z12–Z60 (g/m² one side ×10). Z27 ≈ Z275. |
| CS Type B (A653) | ASTM / ASME | Near | ASTM A653 Commercial Steel Type B, coating G90 (≈ Z275): the US commercial galvanized sheet; no guaranteed mechanicals, C ≤ 0.15. |
| DX52D | EN (European) | Near | Next formability class with guaranteed yield 140–300 MPa — order when DX51D cracks in drawing. |
| 08kp / 08ps galvanized | GOST (Russia/CIS) | Near | GOST 14918 galvanized sheet on 08kp/08ps base, group KhP (cold forming). |
| S250GD | EN (European) | Functional | Structural galvanized grade with guaranteed 250 MPa yield (EN 10346 Table 5) for load-bearing profiles. |
| DC01 | EN (European) | Functional | The uncoated cold-rolled base; DX51D is roughly DC01 substrate plus zinc. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
