Dillidur wear steel 400, 450, 500, 325L, 400V, 500V, 550, IMPACT
Sheet, wear-resistant steel, Dillidur brand, belongs to the group of structural materials of medium hardness, with indicators from 325 to 600 units on the Brinell scale.
in different volumes, includes silicon, manganese, chromium, nickel, molybdenum. The necessary rigidity and strength of the material is also ensured by the use of high-strength hardening technology in production, followed by rapid cooling in water.
Special Properties
Rolled metal made of Dillidur steels, in addition to high strength, stands out for:
– Wear resistance.
– Resistant to aggressive media and abrasives.
– Resistant to dents and cracks.
– Good machinability, flexibility and weldability.
– Durability.
– The ability to retain its properties, as at high temperatures, reaching 500 degrees, and at sufficiently low temperatures.
Applications
High strength and wear resistance of Dillidur steel, widely used in the production of construction machines and other special equipment, loaders, trolleys , crushing and screening and pressing equipment, conveyor elements, grinders and screeners.
