加工
The entire processing and application techniques are of fundamental importance to the reliability of products made from this steel. The user should ensure that his design, construction and processing methods are aligned with the material, correspond to the state-of-the-art that the fabricator has to comply with and are suitable for the intended use. The customer is responsible for the selection of the material.
The recommendations of the EN 1011-2 (Welding) and CEN/TR 10347 (Forming) as well as recommendations regarding job safety in accordance with national rules should be observed.
DILLIMAX 690 Cold forming
冷成型是指在低於最大允許應力消除溫度 (560 °C/1040 °F) 的情況下成型4）.
DILLIMAX 690 can be cold formed with regard to its high yield strength. Flame cut or sheared edges in the bending area should be ground before cold forming. Cold forming is related to a hardening of the steel and to a decrease in toughness. Some codes may limit the maximum permissible strain during cold forming.
Depending on the relevant code this can result in the need of larger bending radiuses than indicated in the chart. For larger cold forming amounts we recommend you to consult the steel producer prior to ordering.
在加工過程中，必須採取必要的安全措施，以免工件在成型過程中可能發生斷裂而造成危險。
通常可以透過冷成型實現以下幾何形狀，而不會形成表面缺陷（其中 t 是板厚度）：
| 最小彎曲半徑 | 最小模具寬度 | |
| 橫向 | 2 t | 7噸 |
| 縱向 | 3噸 | 9噸 |
DILLIMAX 690 Hot forming
若溫度為 560 °C (1040 °F)4） is exceeded, the initial tempering will be altered so that the mechanical properties are affected.
To regain the initial properties new quenching and tempering become necessary. However, water quenching of a formed workpiece or component will often be less effective than the original quenching in the plate mill so that the fabricator may not be able to reestablish the properties required and therefore hot forming may not be suitable.
In this respect we recommend you to contact the steel producer prior to ordering, in all cases where hot forming is required.
最後，製造商有責任通過適當的熱處理獲得所需的鋼材值。
DILLIMAX 690 Welding and flame cutting
Due to its high yield strength, DILLIMAX 690 requires special care during plate processing. For flame cutting, the following minimum preheating temperatures are recommended : 25 °C (77 °F)4） 適用於厚度達 20 毫米（0.8 吋）的板材4）, 50 °C (122 °F)4） for plate thickness up to 50 mm (2 in)4）, 100°C (212°F)4） for plate thickness up to 100 mm (4 in) 4）, 150 °C (302 °F)4） for plate thickness up to 200 mm (8 in)4） and 180 °C (356 °F)4） 對於較厚的板。
For general welding instructions, please consult the EN 1011. In order to ensure that the tensile strength of the weld metal fulfils the requirements of the base metal, the heat input and interpass temperature must be limited during welding. Experience has shown that the welding conditions should be chosen so that the cooling time t8/5 does not exceed 20 seconds. This is applicable when using suitable filler materials of a corresponding yield strength class.
The high yield strength of the base material must be taken into account when choosing the filler materials.
It should be considered that increased heat input leads to lower tensile properties in the weld metal. If a stress relieving heat treatment is planned during or after plate processing, this must also be considered when selecting the filler materials. To avoid hydrogen-induced cold cracking, only filler materials, which add very little hydrogen to the base metal, may be used. Therefore, shielded arc welding should be preferred.
4） The approximately converted values in brackets are for information only.
For manual arc welding, electrodes with basic coating (type HD<5 ml/100 g in accordance with ISO 3690), and dried according to the manufacturer’s instructions, should be used.
