Caterpillar has approved Ruukki’s wear-resistant special steel Raex 400 in accordance with the Caterpillar specification 1E1839. Raex is used in ADT truck’s main body structure. The contract with Caterpillar covers the delivery of Raex to their major European facilities for 2011.
The approval testing was performed at the CAT Peterlee production facility in the UK where the group’s Articulated Dump Truck (ADT) product for global supply is manufactured. The ADT truck’s main body structure is one of the most demanding applications for wear-resistant steel due to the continual impact and wear experienced.
The approval process was demanding. It included chemical, mechanical as well as impact testing and macro’s tests on the weld. Identical tests were performed in large quantity to ensure product consistency.
