What is DX54D Steel?
DX54D is a hot-dip coated deep-drawing steel in the DX series, valued for high formability. Made of low-carbon steel, it's ideal for cold forming. "DX" denotes the series, "54" the formability grade, and "D" the deep-drawing quality. Both DX54D and DX53D are automotive steels, but DX54D has higher formability, making it better for complex shapes. DX54D (equivalent to FeP06G, steel number 1.0952) is used in automotive panels and appliance housings, with corrosion resistance for outdoor or moist conditions.
Chemical Composition of DX54D Steel
| Element | Content (%) |
| Carbon, C | 0.08 max |
| Manganese, Mn | 0.45 max |
| Phosphorus, P | 0.03 max |
| Sulfur, S | 0.03 max |
| Silicon, Si | 0.50 max |
| Aluminum, Al | 0.02-0.07 |
| Nitrogen, N | 0.012 max |
| Titanium, Ti | 0.30 max |
| Chromium, Cr | 0.20 max |
| Nickel, Ni | 0.20 max |
| Copper, Cu | 0.20 max |
Low Carbon (C): Ensures ductility and ease in deep drawing without compromising strength.
Controlled Manganese (Mn): Enhances strength and toughness.
Low Phosphorus (P) and Sulfur (S): Improves weldability and reduces brittleness.
Aluminum (Al): Acts as a deoxidizer, improving surface quality.
Titanium (Ti): Increases stability in forming, reducing cracks and defects during shaping.
Mechanical Properties of DX54D Steel
| Property | Metric | Imperial |
| Tensile Strength | 270 – 370 MPa | 39 – 54 ksi |
| Yield Strength | 120 – 220 MPa | 17 – 32 ksi |
| Brinell Hardness | 90 – 120 HB | 90 – 120 HB |
| Rockwell Hardness | 50 – 65 HRB | 50 – 65 HRB |
| Vickers Hardness | 100 – 130 HV | 100 – 130 HV |
| Elongation | ≥ 36% | ≥ 36% |
| Elastic Modulus | 210 GPa | 30,500 ksi |
| Anisotropy (R-Value, Min) | ≥ 1.6 | ≥ 1.6 |

Moderate Tensile and Yield Strength: Provides enough strength for durability without sacrificing formability, suitable for automotive and appliance parts.
High Elongation: Allows significant stretching, enabling complex shapes without cracking.
Good Anisotropy (R-Value): Ensures consistent properties in different directions, reducing defects in deep-drawn parts.
Stable Strain Hardening Index (n-Value): Supports gradual deformation, which helps maintain structural integrity during shaping.
Application of DX54D Steel
Automotive Industry: Body panels, doors, hoods, and structural components.
Appliance Manufacturing: Refrigerator panels, washing machine housings, and dryer cabinets.
Construction: Roofing, wall panels, and structural frames.
HVAC Systems: Air ducts, furnace casings, and ventilation parts.
Furniture: Shelving units, office desks, and metal frames.
Electrical Enclosures: Circuit boxes, control panels, and transformer housings.
Agricultural Equipment: Tractor panels, plow parts, and protective covers.
Lighting Fixtures: Lamp bases, outdoor lighting enclosures, and reflector frames.
