ArcelorMittal Europe launches new crane rail grade
8 August 2022ArcelorMittal Europe – Long Products’ Rails & Special Sections has launched R340, a top wear performance crane rail grade for heavy loads, allowing customers to optimise their Life Cycle cost. Designed in the ArcelorMittal Rail Excellence Centre (Global R&D), R340 combines optimum process parameters with ad-hoc chemical composition. This new grade with higher mechanical properties and hardness was specifically designed for heavy loads.
Product newsArcelorMittal rails in India’s first rapid rail system
19 July 2022ArcelorMittal Europe – Long Products’ mill in Gijon, Spain is producing rails for the Delhi–Ghaziabad–Meerut Corridor, part of the Regional Rapid Transit System (RRTS) project currently ongoing in India. With trains running at a maximum speed of 180 km/h, the distance between Delhi and Meerut will be covered in less than 60 minutes.

ArcelorMittal Europe launches new crane rail grade
ArcelorMittal Europe – Long Products’ Rails & Special Sections has launched R340, a top wear performance crane rail grade for heavy loads, allowing customers to optimise their Life Cycle cost. Designed in the ArcelorMittal Rail Excellence Centre (Global R&D), R340 combines optimum process parameters with ad-hoc chemical composition. This new grade with higher mechanical properties and hardness was specifically designed for heavy loads.
Top wear performance and increased service life
A specific wear test was designed to assess in-service performance. The results show that R340 is a benchmark in wear resistance compared with other crane rail grades available on the market thanks to its customised microstructure. The combination of customised microalloying in the chemical composition along with a specific rolling process and subsequent air cooling results in this new steel grade with improved hardness and mechanical properties, in addition to a notable life service extension and consequently lower maintenance costs.
“It has been a challenging development due to the ambitious hardness target to be achieved by natural cooling, but with this grade we have gone beyond the limits of the air-cooled pearlitic rail steels. This was possible thanks to the great internal collaboration between the mill and the commercial and R&D teams, which allowed us to achieve good industrial results in record-time. Now we are aiming to go even further. There is already a strong interest from the market and its key players,” concludes Frédéric Goujon, product manager for crane, grooved, and light rails.
R340, which has been approved for welding, has been integrated into the ArcelorMittal crane rails technical specifications and is available on the entire crane and special rails range.

ArcelorMittal rails in India’s first rapid rail system
ArcelorMittal Europe – Long Products’ mill in Gijon, Spain is producing rails for the Delhi–Ghaziabad–Meerut Corridor, part of the Regional Rapid Transit System (RRTS) project currently ongoing in India. With trains running at a maximum speed of 180 km/h, the distance between Delhi and Meerut will be covered in less than 60 minutes.
Three times faster than the metro
The Delhi–Ghaziabad–Meerut Corridor, part of Regional Rapid Transit System (RRTS) project, is the first out of three corridors that will be built in the first phase of the project.
RRTS is a new high-speed system with high capacity, connecting regional nodes in the National Capital Region. It will provide a reliable and comfortable transportation system, three times faster than the metro and aimed at passengers looking to travel longer distances.
22 000 tonnes of rails from Gijon, Spain
ArcelorMittal - Long Products Rails and Special sections was awarded the contract by the National Capital Region Transport Corporation India (NCRTC). It involves the supply of 22 000 tonnes of 60E1 head-hardened 18-metre rails, produced according to Indian specifications.
The rails are being produced in ArcelorMittal's Gijon rail mill and deliveries are spread out over a 24-month period. Shipments from Spain to India are split into four lots. Once they arrive at Mundra port, they are distributed by trucks from the client's depots. Almost half of the volume has already been supplied and deliveries are progressing according to the plan agreed with the client.
Bids for this tender were submitted in February 2020, and offer evaluation lasted until August 2020. This global tender attracted many global competitors and every bidder had to meet strict qualification criteria. After a lengthy evaluation process, ArcelorMittal’s bid emerged as the best proposal. Winning the first stage of this important project will certainly put ArcelorMittal in an excellent position to compete in the following stages.
The Delhi–Ghaziabad–Meerut Corridor is expected to be partially operational in 2023. In Phase 2, five more corridors are expected to be developed.

Useful information
MoreInnovative, high quality rails
The rails and track fittings manufactured by ArcelorMittal are supplied worldwide for high speed tracks, heavy haul tracks, and urban transport systems amongst others thanks to their product quality and the elevated level of reliability which has earned ArcelorMittal the trust of their customers.
The offer is enhanced with many certificates and approvals from transport companies in different countries.
Rails are steel products that must fulfil a multitude of technological requirements. Continuous quality control and elaborate testing ensure the characteristics of the final product meet the stringent requirements regarding rail characteristics and performance.
In addition to head hardened rails, high-speed railways (with speeds over 350 km/h) are one of the most demanding applications for which ArcelorMittal has developed innovative production processes.
