Galvanized Steel Sheet
DX53D (material number 1.0951) is a non-alloy structural steel grade defined under EN 10346, widely used for hot-dip galvanized steel sheets and coils. The "DX" designation indicates drawing quality steel, while "53" represents superior formability compared with standard grades such as DX51D. The zinc coating provides excellent corrosion protection, extending service life and reducing maintenance costs in a wide range of environments.
DX53D galvanized steel sheets are specifically designed for deep drawing and complex forming operations, making them ideal for demanding industrial and commercial applications where high ductility, surface quality, and corrosion resistance are required.
Chemical Composition of DX53D (1.0951)
| Element | C (%) | Mn (%) | P (%) | S (%) | Al (%) |
|---|---|---|---|---|---|
| Typical Max | 0.08 | 0.45 | 0.030 | 0.025 | ≥0.015 |
This low-carbon composition ensures excellent formability, weldability, and stable coating adhesion.
Mechanical Properties of DX53D Galvanized Steel
| Property | Typical Value |
|---|---|
| Yield Strength | 140 – 220 MPa |
| Tensile Strength | 270 – 350 MPa |
| Elongation | ≥36% |
