National wear-resistant steel plate DILLIDUR 550
1.DILLIDUR 550 wear-resistant steel plate introduction
DILLIDUR 550 is a wear-resistant steel plate imported from Germany with a nominal hardness of 550 HBW. The DILLIDUR 550 offers excellent processability and can be selected for use in high-intensity wear environments.
2.DILLIDUR 550 wear-resistant steel plate application
DILLIDUR 550 is widely used in all kinds of construction machinery equipment, conveying equipment, shredder and garbage recovery equipment and other serious wear parts.
3.DILLIDUR 550 wear-resistant steel plate supply size
The DILLIDUR 550 is available in thicknesses of 10-51mm and widths up to 3300mm.

5.DILLIDUR 550 wear-resistant steel plate delivery mechanical properties
6.1 Hardness: Room temperature surface Brinell hardness: 520-580 HBW
6.2 Test: Surface Brinell hardness test once per furnace and every 40 tons.
6.DILLIDUR 550 wear-resistant steel plate heat treatment
The hardness of DILLIDUR 550 comes from accelerated cooling from the austenitizing temperature. In order to have no significant decrease in hardness after hot forming, it is possible to be supplemented by subsequent re-quenching treatment. However, the hardness obtained after re-quenching will be different from the hardness detected at the factory of the steel plate, because the cooling efficiency of the quenching equipment in the processing plant is generally lower than that of the quenching equipment when the steel plate is produced.
This material can be heated to approximately 250°C (482°F) without a significant decrease in hardness.
7.DILLIDUR 550 wear-resistant steel plate delivery status
The steel plate is quenched by controlled warm water or water quenched + tempered. (Unless otherwise agreed, Class A2 applies, with reference to EN 10163-2.)
8.DILLIDUR 550 wear-resistant steel plate processing
The complete set of processing and application technologies adopted by the user are essential to the reliability of the products manufactured from this material, and it should be ensured that the design, construction and processing methods are suitable for this material and meet the latest processing requirements that the processor must follow and the purpose of the product. Users should make their own material selection, and fully consider the characteristics of high strength and high hardness of the material, and follow the process recommendations in line with the national safety production standards.
