Texmaco's foundries push advanced steel tech

Railway castings are the heavy steel parts that sit under wagons and at track junctions, and Texmaco Rail and Engineering says its foundries are now making a newer rail-grade steel for them at industrial scale. (texmaco.in) That newer grade is carbide-free bainitic steel, a type of steel designed for hard-wearing rail service. Research on rail applications says this structure can deliver higher crack resistance and strong mechanical performance than standard pearlitic rail steel after rolling and cooling. (springer.com) Texmaco says the production work is happening inside a steel foundry with installed capacity of 42,000 metric tons a year in Kolkata. The company says the plant is the largest steel casting facility in India’s foundry sector and uses automated molding, simulation software, in-house testing and machining. (texmaco.in) The company’s pitch is not just about metallurgy. Texmaco says it is also using machine-learning methods to tighten process control, improve consistency and scale output for railway castings, a category that includes bogies, couplers and cast manganese steel crossings. (texmaco.in) That matters in a rail supply chain where castings are a bottleneck item: they are safety-critical, they require repeatable chemistry and cooling, and they are harder to replace quickly than fabricated steel parts. Texmaco’s own investor materials say its foundry was running at near 100% utilization in 2024 and sold 41,685 metric tons in fiscal year 2025. (texmaco.in 1) (texmaco.in 2) Texmaco is positioning that capability inside a larger domestic rail manufacturing push. The company says it operates 6 manufacturing units across 6.78 million square feet and supplies wagons, coaches, electric multiple unit parts, steel castings, bridges and rail engineering projects. (texmaco.in) The foundry already holds credentials that matter for export markets as well as Indian orders. Texmaco says it is the only foundry in India with Association of American Railroads M-1003 qualification for exporting railway castings to North America, and it says about 40% of foundry output goes to the United States and Australia in railway and mining equipment. (texmaco.in 1) (texmaco.in 2) The technical claim also fits a wider industry search for steels that last longer in high-wear rail locations such as turnouts and crossings. A 2025 wear study on carbide-free bainitic rail reported five years of industrial service under heavy-load conditions, adding to earlier work that compared the steel favorably with conventional rail grades. (sciencedirect.com) (springer.com) Texmaco’s message is that advanced steelmaking and data-driven quality control belong in the same factory. If the company can keep yields high while pushing newer rail steels into regular production, it strengthens its case to be both a domestic supplier of record and an export foundry for railway castings.
