Suppliers, Traders, Exporters and Stockists of Dillidur 450 Abrasion Resistant Steel Plates
ARK Stainless is a leading supplier, trader, stockist and exporter of Dillidur 450 Abrasion Resistant Steel Plates. DILLIDUR 450 is a wear resistant steel with an average hardness of 450 HBW in delivery condition ex works. Its mechanical properties are obtained by quenching. DILLIDUR 450 is preferentially used by the customers where elevated resistance to wear is required together with good workability and especially good weldability.
Examples of application: earth moving and loading machines, dredgers, skip cars, conveying plants, trucks, cutting edges, knives and breakers, waste elimination and recycling plants.
Dillidur 450 is a wear-resistant steel plate with a nominal hardness of 450 HBW in the delivery state. Recommended for applications in high-wear environments that require materials with excellent machinability, especially excellent welding performance.
Cold forming
DILLIDUR 450 can be cold formed by bending in spite of its high hardness and strength. It should be paid attention to the fact that with increasing yield strength, the required forces for the forming operation also grow, even if the plate thickness remains unchanged. The spring-back also increases. In order to avoid the risk of cracking from the edges, flame cut or sheared edges should be ground in the area that is to be cold formed. It is also advisable to round the plate edge slightly on the outside of the bend coming under tension stress during bending.
During the processing, the necessary safety measures have to be taken, so that nobody will be exposed to a danger by a possible fracture of the work piece during the forming process.
Hot forming
Since DILLIDUR 450 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 through such a treatment may differ from that measured in the 450 a product brand of Dillinger 4/6 delivery condition. This is due to the fact that the cooling conditions at the fabricator's works are generally less effective than those available during plate production. The steel can be heated to about 200 °C (390 °F) without any substantial drop in hardness 250 °C (482 °F) for short period).
Flame cutting and welding
For flame cutting, the following minimum temperatures should be observed: 50 °C (122 °F) for plate thicknesses up to 26 mm, 100 °C (212 °F) for plate thicknesses from 26 up to 52 mm, and 125 °C (257 °F) for thicker plates.
For manual arc welding basic coated rods, having a very low residual moisture should be used (if necessary, drying according to the instruction of the manufacturer should be carried out).
