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 550 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.

Applications
Heavy plate for earthmoving machinery and mining
Many leading manufacturers of earthmoving and mining machinery, around the entire globe, put their trust in Dillinger heavy plate? Because: anyone who produces machines that reliably achieve ultra-high performance under the most adverse service conditions, day in, day out, must also be able to depend on his partners' performance.
