What Is Mechanical Properties of DX54D Steel?

Dec 31, 2025 Leave a message

hot-dip galvanized steel

 

DX54D is alloyed hot-dip galvanized steel, which is a kind of shallow-stretched galvanized steel processed with DC04 as the base material, and the surface is plated with a layer of zinc.

D-Stamping Steel
X-cold rolled or hot rolled
54 – Stamping class (the higher the number, the better the stamping performance)
D – hot-dip coated steel plate

Alloyed high-grade steel DX54D is available in the following hot-dip coatings: DX54D+Z (galvanized), DX54D+ZF (galvanized-iron), DX54D+ZA (galvanized-aluminum), DX54D+AZ (aluminum-zinc), DX54D +AS (aluminum-silicon-coated).

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
Strain Hardening Index (n-Value, Min) ≥ 0.18 ≥ 0.18

 

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.

 

These properties make our DX54D steel ideal for applications that require precision forming and high reliability, helping you to efficiently produce high-quality products that meet your standards.

 

Surface Treatment of DX54D Steel

 

In order to improve the corrosion resistance, wear resistance and appearance of DX54D steel, we provide a variety of surface treatment methods:

Passivation or Chromate Coating: Applied post-galvanizing to prevent oxidation and enhance corrosion resistance.

Phosphating: Promotes paint adhesion, commonly used in automotive and appliance finishes.

Organic or Epoxy Coatings: Provide added protection for parts exposed to wear or extreme environments.
