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.
Inox Steel India supplies tool steel round bars in the following grades:
AISI D2 – High-carbon, high-chromium cold work tool steel with excellent wear resistance
AISI H13 – Chromium hot work tool steel with superior toughness and thermal resistance
AISI O1 – Oil-hardening tool steel for cutting tools and general-purpose tooling
Applicable Standard: ASTM A681
Master Technical Datasheet provided above applies to all grades.
India: Strong demand from tool rooms, die & mold manufacturers, automotive tooling units, and forging die manufacturers in Mumbai, Pune, Ahmedabad, Faridabad, Coimbatore, and Chennai.
