| Packaging size | Standard coils with outside diameters up to 1300 mm. Traverse-wound coils with drum weights up to 500 kg. Multiple-coil up to 3 tons. | |
| Testings | Fatigue strength: The fatigue strength is defined as the maximum bending stress amplitude which a material withstands for 10.000.000 load cycles under symmetrical alternate load without breaking. It depends on the temper selected and can be estimated typically by 1/3 of tensile strength. For solid solution fine grain materials fatigue strength might increase up to 0,5 * of tensile strength. Bending test: 90° bend test According to EN ISO 7438, 180° bend test acc. to ASTM B820, shown values might show orange- peel, however no crack. | |
