DX53D+ZF Galvannealed Steel Sheet
Product Description
DX53D+ZF Galvannealed Steel Sheet is a deep-drawing-quality steel sheet with a zinc-iron alloy coating. Produced through continuous hot-dip galvanizing and subsequent alloying annealing, it combines a formable steel substrate with a metallurgically bonded ZF coating for applications requiring both forming performance and surface protection.
The DX53D substrate is designed for more demanding deformation than general forming and drawing grades. With a minimum elongation of 34%, a minimum plastic strain ratio (r90) of 1.3, and a strain hardening exponent (n90) of 0.16, DX53D+ZF can be considered for components involving deeper drawing and more complex stamping operations.
Also designated as DC53D+ZF in Rosen's published grade cross-reference, this material is relevant to automotive stamped panels, appliance components, formed electrical housings, and other sheet metal products. Its zinc-iron alloy coating also supports subsequent painting and resistance spot welding when the appropriate processing conditions are applied.
Rosen supplies DX53D+ZF Galvannealed Steel Sheets in different dimensions and coating specifications. Buyers can specify sheet thickness, width, length, coating mass, and surface treatment according to their manufacturing requirements.

Deep Drawing Substrate Performance
DX53D is designed for deep drawing applications. Its elongation and plastic deformation characteristics make it suitable for components requiring more substantial forming than conventional general-purpose sheet steel.
Zinc-Iron Alloy Coating
The ZF coating is produced through an additional alloying annealing process after hot-dip galvanizing. The resulting zinc-iron alloy layer has a characteristic matte gray appearance and provides a metallurgically bonded coating structure.
Suitable for Complex Stamped Components
The substrate's mechanical properties support drawing and stamping operations involving greater deformation. Actual forming suitability depends on component geometry, forming depth, tooling design, and lubrication conditions.
Surface Compatibility with Painting
The galvannealed surface provides favorable characteristics for subsequent painting and powder coating. Appropriate cleaning and pretreatment should be selected according to the requirements of the final coating system.
Resistance Spot Welding Compatibility
DX53D+ZF can be considered for resistance spot welding applications. Welding current, electrode pressure, welding time, and electrode maintenance should be optimized according to sheet thickness and coating specifications.
Corrosion Protection for Finished Products
The zinc-iron alloy coating provides sacrificial corrosion protection to the steel substrate. For components requiring additional durability, coating mass and subsequent protective finishing should be evaluated according to the operating environment.
A Range of Forming Grades
Rosen supplies galvannealed steel grades for different forming requirements, including general forming, drawing, deep drawing, and extra-deep drawing. Buyers can compare available grades according to component geometry and deformation requirements.
Flexible Sheet Dimensions
Different thicknesses, widths, and cutting lengths are available within the published product range. This gives manufacturers flexibility when planning material layouts and downstream stamping operations.
Coating and Surface Treatment Options
Rosen offers zinc-iron alloy coated steel with different coating specifications and surface treatment options. Customers can discuss passivation, oiling, and selected chrome-free treatments according to their production requirements.
Material Selection Support
Our team can review the required steel grade, coating mass, sheet dimensions, and intended forming process to help identify suitable material specifications.
DX53D identifies a deep-drawing-quality steel grade under EN 10346, while ZF indicates a zinc-iron alloy coating. The complete designation refers to a deep-drawing steel substrate with a galvannealed surface.
Both grades use zinc-iron alloy coatings, but their substrate forming classifications differ. DX52D is intended for drawing applications, whereas DX53D is designed for deep drawing. DX53D also has higher minimum elongation and specified r-value and n-value requirements in Rosen's published specifications.
Yes. DX53D+ZF can be considered for automotive components involving deep drawing and subsequent painting or welding. Actual suitability depends on the part geometry, deformation level, tooling, lubrication, and coating integrity.
Rosen's published galvannealed steel range includes double-sided coating weights of 80–120 g/m². The required coating specification should be confirmed according to the component's corrosion protection and manufacturing requirements.
Yes. DX53D+ZF can be considered for formed appliance panels, refrigerator components, washing machine parts, and other products involving deep drawing and subsequent surface finishing.
