Default stock condition: hot-dip galvanized drawing-quality coil/sheet for formed, corrosion-protected parts.
What is DX53D Galvanized?
DX53D Galvanized is DX53D supplied in the Galvanized condition — default stock condition: hot-dip galvanized drawing-quality coil/sheet for formed, corrosion-protected parts. DX53D Galvanized has a yield strength of 200 MPa (29 ksi) and a tensile strength of 320 MPa (46.4 ksi) — weaker than 98% of steel grades. Elongation at break is 36% and the elastic modulus is 210 GPa (30.5 Msi). DX53D Galvanized has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,495°C (2,723 °F). HR is the default condition FabDigit quotes; Galvanized is available on request or by drawing note.

Working with DX53D Galvanized
Is DX53D easy to machine?
Soft and gummy — use sharp positive-rake tools, high speed and low feed on blanked or punched sheet; deburr edges since cut edges lose coating.
Can DX53D be welded?
Excellent resistance spot/seam and MAG weldability, but extract zinc fumes, raise current ~10–20 % versus bare steel and expect porosity/spatter; touch up welds with zinc-rich paint.
Can DX53D be formed, bent or molded?
Drawing-quality: suits deep drawing, stretch forming and tight roll-formed profiles; order skin-passed non-ageing material and use zinc-friendly lubricant to avoid galling and powdering.
What surface finishes work on DX53D?
Not anodizable — phosphate/chromate-free passivate then powder-coat or coil-coat; oiled or passivated coils must be kept dry to avoid white rust.
DX53D chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |

| Ccast analysis, EN 10346 | ≤ 0.12 | 0.04 |
| Mn | ≤ 0.6 | 0.25 |

DX53D Galvanized — frequently asked
What is DX53D Galvanized used for?
DX53D Galvanized is typically used for deep-drawn appliance housings, HVAC ducting and plenums, cable trays and trunking, roof and wall cladding panels, automotive underbody brackets and roll-formed purlins and profiles. In short: drawing galvanized coil.
What is the yield strength of DX53D Galvanized?
DX53D Galvanized has a typical yield strength of 200 MPa (29 ksi) and a tensile strength of 320 MPa (46.4 ksi) — weaker than 98% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is DX53D Galvanized easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed and low feed on blanked or punched sheet; deburr edges since cut edges lose coating.
Can DX53D Galvanized be welded?
Yes — weldability is rated very good (75/100). Excellent resistance spot/seam and MAG weldability, but extract zinc fumes, raise current ~10–20 % versus bare steel and expect porosity/spatter; touch up welds with zinc-rich paint.
What surface finishes work on DX53D Galvanized?
Not anodizable — phosphate/chromate-free passivate then powder-coat or coil-coat; oiled or passivated coils must be kept dry to avoid white rust.
Can DX53D Galvanized be formed, bent or molded?
Drawing-quality: suits deep drawing, stretch forming and tight roll-formed profiles; order skin-passed non-ageing material and use zinc-friendly lubricant to avoid galling and powdering.
What is the maximum service temperature of DX53D Galvanized?
DX53D Galvanized is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between DX53D-HR and DX53D-CR?
HR is the default condition — hot-rolled pickled base used for the heavier gauges of DX53D coated strip; slightly lower ductility and rougher surface than CR. CR: uncoated cold-rolled full-finish base metal; pick when the part is painted or coated after forming, or for inland/indoor use. Yield strength is 220 MPa in HR versus 190 MPa in CR.
