Dhruv Metals, a prominent manufacturer and supplier located in Hyderabad, India, is known for its top-notch Tool and Die Steel O1 Bars. With a solid reputation for producing high-performance steel products, Dhruv Metals serves a diverse array of industries that demand precision and durability. The company prides itself on delivering consistent quality, competitive pricing, and timely deliveries, all aimed at ensuring complete customer satisfaction. Thanks to its advanced manufacturing capabilities and rigorous quality control standards, Dhruv Metals has become a trusted name in the tool steel market, especially for O1 grade bars, which are celebrated for their machinability and hardness.
Tool and Die Steel O1 Bars are oil-hardening, non-deforming steels that boast a high carbon and chromium content. Their typical chemical makeup includes: Carbon (0.90–1.00%), Chromium (0.50–0.60%), Manganese (1.00–1.20%), along with trace amounts of Silicon and Vanadium. O1 steel is known for its excellent dimensional stability during heat treatment, achieving a Rockwell hardness of up to 64 HRC when hardened. With impressive wear resistance and toughness, O1 steel keeps its cutting edge sharp even under high stress, making it perfect for precision tooling applications.

When choosing O1 tool and die steel bars, consider factors like hardness, wear resistance, machinability, heat treatment requirements, intended application (e.g., cutting, stamping), and cost-effectiveness for long-term use.
O1 tool and die steel bars have moderate resistance to corrosion due to their carbon content and alloy composition. However, they are not stainless and can rust without proper maintenance, such as coating or regular oiling.
These Tool and Die Steel O1 Bars are extensively utilized in crafting precision tools and dies, thanks to their remarkable hardness, edge retention, and machinability. You’ll find them in a variety of applications, including punches, dies, cutting tools, knives, broaches, gauges, and industrial blades. Their dimensional stability during heat treatment makes them ideal for close-tolerance work. O1 steel is also well-suited for cold working applications where moderate wear resistance and toughness are crucial. Industries such as automotive, aerospace, plastic molding, and general engineering depend on O1 bars to produce high-performance components that require precision and durability, even in the toughest operational conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
