Examples of application are extremely stressed parts in earth moving machines, conveyors, crushers and recycling plants.
DILLIDUR 600 can be cold formed to only a limited extend because of its high hardness and strength. In case of such applications please contact the customer service.
The plates are water quenched or water quenched and tempered under controlled conditions.
General technical delivery requirements: Unless otherwise agreed, the general technical delivery requirements in accordance with EN 10021 apply.
|Flame cutting and welding|
For flame cutting, the following minimum preheating temperature should be observed: 175 °C (347 °F) for all thicknesses.
After flame cutting, attention should be paid to a slow cooling, e.g. by using thermal blankets. This will reduce the risk of hydrogen-induced cracking.
When using ferritic filler materials, attention should be paid to very low hydrogen content and the following preheating temperatures have to be observed: 180 °C (356 °F) for plate thicknesses up to 60 mm (2.4 in.).
When using soft austenitic filler materials, a preheating temperature of 50 °C (122 °F) is normally sufficient.
To avoid a hardness loss, the preheat and interpass temperature for flame cutting and welding irrespective of the applied process should not exceed 180 °C (356 °F).
For manual arc welding, basic coated rods with very low residual moisture should be used (and dried if necessary according to the manufacturer’s instructions).
If particular requirements, which are not covered in this material data sheet, are to be met by the steel due to its intended use ore processing, these requirements are to be agreed before placing the order.
The information in this technical data sheet is a product description. This material data sheet is updated at irregular intervals.
Since DILLIDUR 600 obtains its hardness by accelerated cooling from the austenitizing temperature, hot forming without major hardness loss is only possible if a renewed quenching treatment is carried out after forming. However, the hardness achieved by means of such a treatment may differ from that measured in the delivery condition. This is due to the fact that the cooling conditions at the fabricator’s works are generally less adequate than those available during plate production. The steel can be heated, short time, to about 180 °C (356 °F) without any substantial drop in hardness.
DILLIDUR 600 can be machined by using sharp carbide tools in spite of its very high hardness. It should be ensured that adequate heavy machine tools, adequate feed and cutting speeds are applied.
DILLIDUR 600 can be delivered in thicknesses from 15 mm (0.6 in.) to 60 mm (2.4 in.) and in the following maximum widths:
Identification of plates: Unless otherwise agreed the marking is carried out via steel stamps with at least the following information:
The steel is fully killed and fine grain treated.
The entire processing and application techniques are of fundamental importance to the reliability of the 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. Recommendations regarding job safety in accordance with national rules should be observed while considering the higher strength and high
Unless otherwise agreed, the specifications will be in accordance with EN 10163-2, class A2.
Brinell surface hardness tested once per heat and 40 t.
Unless otherwise agreed, the tolerances will be in accordance with EN 10029, with class A for thickness.
