ArcelorMittal Rails & Special Sections launches R340, a top wear performance crane rail grade for heavy loads, allowing customers to optimise their Life Cycle cost.
Designed in our ArcelorMittal Rail Excellence Center (Global R&D), R340 combines optimum process parameter with ad-hoc chemical composition. This new grade with higher mechanical properties and hardness was specifically designed for heavy loads.
A specific wear test was designed to assess in-service performance. The results show that R340 is benchmark in wear resistance compared with other crane rail grades available in the market thanks to the customised microstructure.
Our new R340 grade, which is approved for welding, is now integrated in the ArcelorMittal crane rails technical specifications and is available on the entire crane and special rails range.
