DX53D is an advanced deep drawing grade hot dip galvanized steel in accordance with EN 10346, designed for manufacturing precision formed parts with extremely high requirements for ductility and surface integrity. Wanzhi Group provides DX53D coils/sheets with customized coatings (galvanized/galvanized/zinc aluminum magnesium alloy) for applications such as construction, automotive, and home appliances.
DX53D Chemical Composition and Mechanical Properties
DX53D +Z/+AZ/+ZAM substrate adopts a low carbon and high manganese design to ensure the formability and weldability of the coated steel. In addition, the low yield strength and high elongation also ensure the formability, load-bearing capacity, and large deformation processes such as complex bending of the steel.
| Parameter | Value |
| Chemical Composition (wt%) | C ≤ 0.12, Mn ≤ 0.60, P ≤ 0.10, S ≤ 0.03, Al ≥ 0.015 |
| Coating Type | Pure Zinc (Z) or Zinc-Iron Alloy (ZF) |
| Coating Mass | Z50~Z275 (g/㎡) |
| Substrate Thickness | 0.12~6.0mm |
| Yield Strength (ReH) | 140~220 MPa (Typical 170 MPa) |
| Tensile Strength (Rm) | 270~350 MPa (Typical 310 MPa) |
| Elongation (A80) | ≥22% (Typical 28%) |
Core Features and Advantages
DX53D is an upgraded version of DX51D/DX52D, with the best formability. It takes ultra-deep stamping, corrosion resistance and cost-effectiveness as its core advantages, and achieves a balance between strength and ductility.
- Ultra-deep stamping: elongation ≥22%, low yield strength (170 MPa), pure zinc coating, suitable for multiple stamping and the coating is not easy to crack or fall off.
- Corrosion resistance: The coating quality Z20~Z350 can meet the needs of outdoor use for 10~50 years (depending on the environmental corrosion).
- Welding adaptability: It can be used for resistance spot welding and laser welding with excellent adaptability, and the weld strength is more than 80% of the substrate.
- Surface painting: The surface can be directly painted (such as PPGI/PPGL pre-coating).
- Cost-effectiveness: Compared with high-strength steel (such as DX56D), DX53D is cheaper.
Application of DX53D Galvanized Steel
DX53D+Z galvanized steel is the preferred material for processing parts of medium complexity in the fields of automobiles, home appliances, construction, etc. Its design takes into account both processability and durability, which not only meets the needs of complex processes, but also reduces long-term maintenance costs.
- Automobile manufacturing: automobile fuel tanks, wheel arch door inner panels, engine hoods, chassis crossbeams.
- Home appliance industry: oven cavity, washing machine drum, refrigerator liner, washing machine shell, air conditioning radiator.
- Building components: solar bracket system ZM coating, light steel keel, ventilation ducts, solar brackets.
- Transportation facilities: highway guardrails, subway track fixings.
