Supplying high-toughness, fatigue-resistant electrodes & wires for locomotive bogies, passenger coaches, wagons, and track infrastructure.
Railway rolling stock is subject to continuous cyclic dynamic loading, track vibration, and harsh climate extremes across India's vast network. Weld failure in locomotive bogies or freight wagons can lead to catastrophic consequences.
Magnarc is an approved supplier under RDSO guidelines, delivering low-hydrogen MMA electrodes with verified Charpy impact toughness at sub-zero temperatures, and precision copper-coated MIG wires for automated coach shell fabrication.
Tailored consumables engineered specifically for rolling stock components and maintenance operations.
