EN 10346 is a European standard that specifies the requirements for continuously hot-dip coated steel flat products. The DX series, including DX51D, DX52D, DX53D, DX54D, and DX55D, are grades within this standard that are specifically designed for cold forming applications. These grades are commonly used in the automotive industry for manufacturing flat welded steel tubes due to their excellent formability and corrosion resistance.
The chemical composition of these steel grades is crucial for their performance characteristics. Below is a table presenting the typical chemical composition for these grades:
| Element | DX51D | DX52D | DX53D | DX54D | DX55D |
|---|---|---|---|---|---|
| C (max) | 0.12% | 0.12% | 0.12% | 0.12% | 0.12% |
| Si (max) | 0.50% | 0.50% | 0.50% | 0.50% | 0.50% |
| Mn (max) | 0.60% | 0.60% | 0.60% | 0.60% | 0.60% |
| P (max) | 0.10% | 0.10% | 0.10% | 0.10% | 0.10% |
| S (max) | 0.045% | 0.045% | 0.045% | 0.045% | 0.045% |
| Al (min) | 0.015% | 0.015% | 0.015% | 0.015% | 0.015% |
The mechanical properties of these grades are tailored to meet the demands of cold forming and welding. The table below outlines the typical mechanical properties:
| Property | DX51D | DX52D | DX53D | DX54D | DX55D |
|---|---|---|---|---|---|
| Yield Strength (MPa) | ≥140 | ≥140 | ≥140 | ≥140 | ≥140 |
| Tensile Strength (MPa) | 270-500 | 270-420 | 270-380 | 270-350 | 270-330 |
| Elongation (%) | ≥22 | ≥26 | ≥30 | ≥34 | ≥38 |
The DX series grades are differentiated primarily by their formability and mechanical properties. As the grade number increases, the material generally offers better formability and ductility, making DX55D the most formable among them.
These steel grades are extensively used in the automotive industry for manufacturing components such as:
Additionally, they are used in other industries for applications like:
Depending on the specific requirements, alternative grades may be considered. These include:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
