DX51D equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for DX51D across standard systems. Each match is graded so you can see how safe the substitution is. Hot-dip coated low-carbon steel for bending and profiling — full DX51D data sheet.
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 = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.
How the matches are graded
Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.
