Inox Steel India is a trusted manufacturer, supplier, and exporter of Tool Steel Round Bars in premium grades AISI D2, AISI H13, and AISI O1, supplied in accordance with ASTM A681 specifications.
Our tool steel round bars are widely used in tool rooms, die & mold manufacturing, automotive tooling, forging dies, cutting tools, and heavy industrial tooling, where hardness, wear resistance, and dimensional stability are critical.
With ready stock availability in annealed condition and precision-controlled sizes, Inox Steel India supports tool makers, OEMs, and export buyers across India, GCC, Middle East, Africa, Europe, and the Americas.
Tool steel round bars are high-carbon, alloyed steel bars specifically designed for tooling, cutting, forming, and die applications. These steels are engineered to maintain high hardness, edge retention, and resistance to wear and deformation, even under repeated stress.
At Inox Steel India, tool steel round bars are produced through controlled metallurgical processes to ensure uniform microstructure and predictable heat treatment response.
This process ensures tool steel round bars with consistent hardness potential and reliable performance during heat treatment.
These characteristics make tool steel round bars essential for dies, punches, molds, cutting blades, and industrial tooling components.
