DX53D steel
DX53D is a low-carbon, cold-forming steel, mainly iron with small carbon and alloying elements. The "DX" shows its drawing-grade steel, "53" indicates higher formability, and the second "D" means it's hot-dip galvanized for rust resistance. Known for deep drawing, DX53D suits complex shapes and thicker sections needing shape retention and flexibility. Equivalent to EN FeP05G and numbered 1.0951 in EU standards, it's used in automotive, construction, and machinery.
DX: The first letter D stands for flat steel for cold forming, and the second letter X stands for the rolled state of the unspecified base material.
51~57: The numbers indicate the steel grade number; the D after the two digits is the code for hot-dip galvanizing. Z means the coating is pure zinc, ZF means galvanized iron alloy, AZ means galvanized.
Alloy high-grade steel DX53D (deep-drawn quality) is available in the following hot-dip coatings: DX53D+Z (galvanized), DX53D+ZF (galvanized-iron), DX53D+ZA (galvanized-aluminum), DX53D+AZ (aluminum-coated) Zinc), DX53D+AS (aluminum-silicon).
DX53D Steel Production Processes
At GNEE STEEL, we have strict control over every step of the production process to ensure that DX53D steel meets the highest quality standards. Our processes not only guarantee the excellent performance of the steel, but also make it safe for you to use in practical applications, providing a long-term and reliable solution.
Substrate Selection
We use DC01 or DC03 low carbon steel, which has good ductility and easy processing. The low carbon content (C ≤ 0.12%) and the appropriate amount of titanium (Ti ≤ 0.30%) increase the flexibility of the steel, making complex forming easier and avoiding brittleness.
Hot Rolling
Through high temperature hot rolling, the steel thickness is precisely controlled, which enhances strength and ductility. This ensures that the steel is more stable and reliable in subsequent processing.
Cold Rolling
Cold rolling further optimizes the grain structure of the steel, improves thickness consistency and surface quality, and also improves tensile strength (270-370 MPa), suitable for precision processing and high standards.
Annealing Treatment
Annealing heating can effectively release stress during processing and increase the elongation of steel (30-40%). This makes it more flexible in complex forming and can easily cope with difficult processing requirements.
Galvanizing Treatment
Finally, the steel is hot-dip galvanized to increase corrosion resistance and extend service life. Whether in humid environments or outdoor applications, DX53D can perform stably. Low nitrogen design (≤ 0.012%) ensures better weldability and durability.
