DX54D+ZF Galvannealed Steel Sheet
Product Description
DX54D+ZF Galvannealed Steel Sheet is a special deep-drawing steel product featuring a zinc-iron alloy coating. It combines an interstitial-free (IF) steel substrate with a galvannealed surface, making it suitable for sheet metal components that require substantial deformation during manufacturing.
The material is produced through hot-dip galvanizing followed by alloying annealing. During this process, iron diffuses into the zinc coating to form a zinc-iron alloy layer, giving the finished steel sheet its characteristic matte gray appearance. The ZF coating also provides a suitable surface for subsequent painting and resistance spot welding.
With a minimum elongation of 35%, a plastic strain ratio (r90) of at least 1.4, and a strain hardening exponent (n90) of at least 0.18, DX54D+ZF is designed for more demanding forming operations than conventional drawing grades. It can be considered for complex automotive stamped components, appliance panels, formed metal housings, and other products requiring controlled material flow during deep drawing.
Also identified as DC54D+ZF in Rosen's published material specifications, this grade provides an option for manufacturers seeking a combination of special deep-drawing capability and zinc-iron alloy surface protection.
Rosen supplies DX54D+ZF Galvannealed Steel Sheets in different dimensions and coating specifications. Customers can discuss their required thickness, width, sheet length, coating mass, and surface treatment according to their production needs.

Product Features
Special Deep Drawing Capability
DX54D is designed for special deep drawing applications. Its low yield strength and favorable elongation characteristics support substantial deformation during forming, making it suitable for components with demanding draw depths and geometries.
Interstitial-Free Steel Substrate
DX54D uses an interstitial-free steel substrate according to Rosen's published material classification. This substrate composition supports the high formability requirements associated with special deep drawing applications.
Zinc-Iron Alloy Coating
The ZF coating is formed through an additional alloying annealing process after hot-dip galvanizing. The resulting zinc-iron alloy layer provides a metallurgically bonded surface with a characteristic matte gray finish.
Suitable for Painting and Surface Finishing
The galvannealed surface offers favorable characteristics for subsequent painting and powder coating. Proper surface preparation should be selected according to the final coating system and appearance requirements.
Resistance Spot Welding Compatibility
DX54D+ZF can be considered for resistance spot welding in automotive and industrial manufacturing. Welding parameters should be established according to material thickness, coating specifications, electrode conditions, and production requirements.
Formability for Complex Components
Its elongation, plastic strain ratio, and strain hardening exponent provide useful indicators when evaluating the material for complex forming operations. Actual forming performance should be verified through component-specific stamping trials.
Multiple Deep Drawing Grades
Rosen supplies galvannealed steel across different forming categories, from general forming to special deep drawing and extra-deep drawing. This gives manufacturers more flexibility when matching steel grades to component geometries and stamping requirements.
Material Specifications for Different Applications
Customers can discuss steel grade, coating mass, thickness, width, and surface treatment according to their intended manufacturing process. This helps avoid selecting materials based on coating type alone without considering substrate formability.
Steel Sheet and Coil Supply
Rosen supports both galvannealed steel sheet and coil supply, with slitting and cut-to-length processing options available for different production requirements.
Surface Treatment Selection
Different surface treatment options can be discussed according to storage, lubrication, painting, and welding requirements. The final specification should be confirmed before production.
DX54D identifies a special deep-drawing steel grade under EN 10346, while ZF represents a zinc-iron alloy coating. Together, DX54D+ZF describes a special deep-drawing steel substrate with a galvannealed surface.
DX53D+ZF is designed for deep drawing, while DX54D+ZF is intended for special deep drawing applications. According to Rosen's published specifications, DX54D+ZF has lower yield strength and higher minimum elongation, r90, and n90 values, making it suitable for evaluating more demanding forming requirements.
Yes. DX54D+ZF can be considered for automotive components involving complex drawing and stamping operations. The final material selection should consider draw depth, component geometry, tooling, lubrication, and coating integrity.
Interstitial-free steel is designed to support improved formability by controlling interstitial elements such as carbon and nitrogen. This makes it relevant to applications requiring greater deformation during drawing and stamping. Actual performance depends on the complete steel composition and processing conditions.
Yes. The galvannealed zinc-iron alloy surface is suitable for subsequent painting and resistance spot welding. Appropriate surface pretreatment and welding parameters should be established according to the coating specification and production conditions.
Rosen's published galvannealed steel range covers thicknesses of 0.5–2.5 mm, widths of 800–1800 mm, and sheet lengths of 1000–6000 mm. Specific DX54D+ZF combinations should be confirmed before ordering.
Please provide the required steel grade, thickness, width, sheet length, coating weight, surface treatment, order quantity, and intended application. Drawings or component specifications can also help evaluate material suitability.
