Hard on wear, but easy to work and weld

DILLIDUR has been a fixed part of the global battle against cost-intensive wear for more than 50 years. Initial equippers and producers of wear-parts use these hardened proprietary steels with great success in many sectors, including earthmoving machinery and mining. Thanks to its decades of further development, DILLIDUR provides a unique combination of high resistance to wear and easy working and welding.

The strengths of DILLIDUR proprietary steel

  • The steel composition of DILLIDUR, optimised to achieve high wear-resistance combined with pleasant working and welding, permits low preheat temperatures for welding and flame-cutting. This assures greater reserves in workshop fabrication and for on-site repairs under adverse conditions.
  • DILLIDUR steels are available with hardnesses ranging from 325 to 600 Brinell to withstand maximum exposure to wear.
  • Many thick-walled wear-exposed components, such as high-capacity shovels for punishing service in mines, for instance, need special resistance to cracking. The solution then is DILLIDUR IMPACT, a steel possessing verified extremely high toughness.
