Mechanical Properties, in the state of delivery condition
Grade | Minimum yield point(ReH Mpa) | Tensile strength Rm Mpa | Minimum elongation A(Lo=5.65 √So)% |
COR-TEN A | 355 | 470-630 | 20 |
In case of cold rolled material the yield point is min.310mpa and the tensile strength min. 445mpa. Furthermore cold rolled sheets ≤3mm in thickness made of steel grade COR-TEN A for increased demand to the cold formability is available.Mechanical properties: Yield point min. 275mpa. Tensile strenth min.410mpa; elongation min 25%.
