Working with DX53D-HR
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.

DX53D-HR — frequently asked
What is DX53D-HR used for?
DX53D-HR 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-HR?
DX53D-HR has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 330 MPa (47.9 ksi) — weaker than 98% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is DX53D-HR 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-HR be welded?
Yes — weldability is rated excellent (90/100). 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-HR?
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-HR 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-HR?
DX53D-HR 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.
