Tests on every heat treated plate may be possible on request. The test pieces are taken and prepared according to part 1 and 6 of EN 10025.
The tensile test is carried out on specimens of gauge length Lo = 5.65⋅√So respectively Lo = 5⋅do, in accordance with EN ISO 6892- 1. Tensile tests according to ASTM A370 may be agreed. The impact test will be carried out on Charpy-V-specimens in accordance with EN ISO 148-1 using a 2 mm striker. Unless otherwise agreed, the test will be performed at the lowest temperature of the corresponding quality on transverse test pieces.

Memproses
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
Pembentukan sejuk bermakna pembentukan di bawah suhu pelepasan tekanan maksimum yang dibenarkan (560 °C/1040 °F)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.
Semasa pemprosesan, langkah-langkah keselamatan yang perlu perlu diambil, supaya tiada siapa yang akan terdedah kepada bahaya oleh kemungkinan keretakan bahan kerja semasa proses pembentukan.
Geometri berikut biasanya boleh dicapai dengan pembentukan sejuk tanpa pembentukan kecacatan permukaan (di mana t ialah ketebalan plat):
| Jejari lenturan minimum | Lebar die minimum | |
| Arah melintang | 2 t | 7 t |
| Arah membujur | 3 t | 9 t |
DILLIMAX 690 Hot forming
Jika suhu 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.
Akhir sekali, adalah menjadi tanggungjawab fabrikasi untuk mendapatkan nilai keluli yang diperlukan melalui rawatan haba yang sesuai.
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) untuk ketebalan plat sehingga 20 mm(0.8 in)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) untuk plat tebal.
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.

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.
