Grades: D2, H11, H13 | Supplier & Exporter
Inox Steel India is a trusted manufacturer, supplier, and exporter of tool steel flat bars in India, offering premium-quality D2, H11, and H13 flat bars for critical tooling and high-performance applications.
Our tool steel flat bars are produced from carefully alloyed tool steels using controlled hot rolling and forging processes, followed by annealing to ensure uniform structure and machinability. These flat bars are engineered to deliver high hardness, excellent wear resistance, thermal stability, and long tool life, making them ideal for dies, molds, cutting tools, and hot-work applications.
Buyers searching for tool steel flat bars, tool steel flat bar for sale, steel flat bar near me, or wanting to understand what is flat bar steel used for in tooling rely on Inox Steel India for certified material, consistent quality, and dependable supply from Mumbai.
A tool steel flat bar is a solid rectangular bar manufactured from high-alloy tool steel, designed specifically for tooling, cutting, forming, and hot-working operations. Unlike mild or alloy steel flat bars, tool steels are formulated to achieve very high hardness after heat treatment, while maintaining resistance to wear, deformation, and thermal fatigue.
Tool steel flat bars are commonly used where components must retain sharp edges, resist abrasion, or withstand repeated heating and cooling cycles.
These properties make tool steel flat bars essential in tool rooms, forging units, die casting plants, and heavy manufacturing facilities.
In India, tool steel flat bars see strong demand in Mumbai, Pune, Ahmedabad, Chennai, Coimbatore, and Bengaluru, driven by tool rooms, automotive OEMs, forging industries, and die casting units.
Globally, D2 and H13 flat bars are exported to GCC countries, Africa, Europe, and North America, where precision tooling and long tool life are critical for manufacturing efficiency.
With dispatch from JNPT (Mumbai), Mundra, and Hazira ports, Inox Steel India ensures timely delivery, export-compliant packaging, and complete traceability.
