Processing performance
The whole set of processing technology and application technology used by the user is very important to the reliability of the product made from this material. It should be ensured that the design, structure and processing method are suitable for this material and meet the latest processing requirements and the purpose of the product that the processor must follow. Purpose requirements. The user should select the material by himself, and fully consider the high strength and high hardness of the material, and follow the process recommendation that meets the national standards for safe production.
Pembentukan sejuk
Although DILLIDUR 550 is too high in hardness and strength, the room for cold forming is limited, and you must consult in advance.
Kekerasan daripada hot forming/heat treatment DILLIDUR 550 comes from accelerated cooling from the austenitizing temperature. If the hardness does not decrease significantly after hot forming, it is possible to supplement the 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 250°C (482°F) without a significant decrease in hardness.
Flame cutting and welding:
For all thickness steel plates, the following minimum preheating temperature should be followed during flame cutting: 175°C (347°F)
After flame cutting, measures should be taken to maintain slow cooling. For example, insulation wool can be used, which will reduce the risk of hydrogen-induced cracking.
When using ferritic welding consumables, care should be taken to select very low hydrogen content welding consumables and follow the following preheating temperature: 150°C (302°F) for thickness 15mm and below; 200°C (392°F) for thickness above 15mm F)
When using soft austenitic welding consumables, the preheating temperature of 50°C (122°F) is usually sufficient.
In order to avoid the decrease in hardness, the preheating temperature and interlayer temperature corresponding to flame cutting and welding should not exceed 250°C (482°F).
Manual arc welding should use alkaline-coated electrodes with residual moisture in the ground (if necessary, they should be dried according to the requirements of the electrode manufacturer).
Pemesinan
Despite its extremely high hardness, DILLIDUR 550 can still be machined by using sharp carbide tools. It is necessary to ensure that a heavy-duty processing machine tool is used, and an appropriate feed speed and cutting speed are used.
