1. Mechanical properties of hot dip Al-Zn base
Mechanical properties of steel sheet and strip should be in conformity with the stipulations of following chart.
Because the effects of aging, mechanical properties of the steel strip shall deteriorate with storage time passing, E.g. yield strength and tensile strength will rise, elongation after fracture decreases, formability deteriorates etc. it is suggested to use the material as soon as possible.
| Grade | Tensile test | ||
| Yield strength (Mpa) | Tensile strength (Mpa) | Elongation A80% | |
| DC51D+AZ | - | 270~500 | 22 |
| DC52D+AZ | 140~300 | 270~420 | 26 |
| DC53D+AZ | 140~260 | 270~380 | 30 |
| DC54D+AZ | 120~220 | 270~350 | 36 |
For products with nominal thickness greater than 0.50mm, but less than or equal to 0.70mm, the elongation after fracture is allowed to decrease by 2 units. For products with nominal thickness not greater than 0.50mm, the elongation after fracture is allowed to decrease by 4 units.
