Mechanical properties
Steel for enamelling has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
Tata Steel | Grade | Ymvit Ultra 04 |
---|---|---|
EN 10209: 2013 | Grade | DC04ED |
Max. yield strength Re 1,2,3 | N/mm² | 210 5, 6 |
Tensile strength Rm | N/mm² | 270 - 350 |
Elongation 3 | % | 38 |
r-value | r90 | - |
ravg | - | |
FLD | Yes/No | Yes |
1. The values of the yield strength are those of the 0.2% yield strength for products that do not present a definite yield point, and the lower yield strength ReL for the other products.
2. For a thickness of 0.5 mm < t < 0.7 mm the maximum value of the yield strength is increased by 20 N/mm² and the minimum elongation after fracture is decreased by 2%.
3. For a thickness of t ≤ 0.5 mm the maximum value of the yield strength is increased by 40 N/mm² and the minimum elongation after fracture is decreased by 4%.
Elongation after fracture A uses test piece length L0 = 80 mm.
4. The r value applies to a thickness of t ≥ 0.5 mm.
For a thickness of t > 2 mm, the r value is decreased by 0.2.
5. For a thickness of t ≥ 1.5 mm the maximum value of the yield strength is 225 N/mm².
6. For design purposes, a lower yield strength ReL of at least 120 N/mm² can be assumed.
