DILLIDUR 500 Processing performance
The whole set of processing technology and application technology adopted by the user is very important to the reliability of the products made from this material. It should be ensured that the design, construction and processing methods are suitable for this material, and meet the requirements of the latest processing technology and the purpose of the product that the processor must follow. The user should select the material by himself, and fully consider the high strength and high hardness of the material, and follow the process recommendations that comply with EN 1011-2 (welding) and CEN/TR 10347 (forming), and comply with national regulations for safe production.

Pembentukan dingin
Although DILLIDUR 500 has high hardness and high strength, it can still be cold formed by bending. It should be noted that as the yield strength increases, the forming force required for the steel plate of the same thickness will also increase, and the resilience will also increase. In order to avoid the risk of edge cracking, the flame cut or sheared edge of the cold bending area should be polished. In addition, it is also recommended to smoothly polish the outer edge of the bend that is subjected to tensile stress during bending.
Selama pemrosesan, tindakan keselamatan yang diperlukan harus diambil untuk memastikan bahwa personel tidak terkena bahaya terbang dari benda kerja selama pencetakan.
Pembentukan dingin biasanya dapat mencapai parameter berikut tanpa cacat permukaan (t adalah ketebalan pelat):
| Radius lentur minimum | Lebar bukaan cetakan minimum | |
| Horisontal | 7 t | 16 t |
| Vertikal | 9t | 20 t |
kekerasan dari pembentukan panas DILLIDUR 500 comes from the accelerated cooling of the austenitizing temperature. If the hardness does not decrease significantly after hot forming, it must be supplemented by subsequent re-quenching treatment. However, the hardness obtained after re-quenching will be different from the hardness tested when the steel plate leaves the factory. This is because the cooling efficiency of the quenching equipment in the processing plant is generally lower than that of the quenching equipment during the production of steel plates.
This material can be heated to about 200°C (390°F) without a significant decrease in hardness.
Pemotongan dan pengelasan api
Flame cutting should follow the following minimum preheating temperature: plate thickness 26mm and below, 60°C (140°F);
plate thickness 26~70mm and below, 120°C (248°F); plate thickness above 70mm , 150°C (302°F).
Pengelasan busur manual harus menggunakan elektroda berlapis alkali dengan sisa kelembaban rendah (jika perlu, perawatan kering harus dilakukan sesuai dengan persyaratan pabrikan elektroda).
Selain itu, saran-saran berikut juga perlu diperhatikan:
- For more information on the preheating of DILLIDUR 500, please refer to the technical manual “DILLIDUR-Anti-wear concept”. In any case, preheating above 200 °C (390 °F) must be avoided because it will cause the hardness to decrease (see the figure below).
- It is best to use low yield strength welding consumables for tack welding, root bead and filler bead. If the welding point needs to withstand wear, only use the wear-resistant welding material that can produce the hardness of the mother board in the last weld pass.
Perawatan panas
The following figure shows the general change in hardness or strength with heat treatment temperature:
