Known for their precision and durability, these steel bars are designed to meet the demanding needs of tool-making, die production, and high-performance molds. With a commitment to quality, Sabra Metals employs advanced production techniques and rigorous quality control to guarantee consistent hardness, machinability, and dimensional stability. Catering to industries like automotive, electronics, and general manufacturing, the company ensures that their products perform reliably even under repetitive stress. With a strong emphasis on quality and customer satisfaction, Sabra Metals has become a trusted partner for Tool and Die Steel solutions around the globe.
Tool and Die Steel O1 bars are made from oil-hardening, medium-carbon alloy steel, typically featuring about 0.90% carbon, 1.0% manganese, 0.50% chromium, and 0.40% tungsten. This specific composition delivers outstanding wear resistance, toughness, and uniform hardness after heat treatment. O1 steel bars can be hardened to a range of 57–62 HRC, providing excellent dimensional stability that makes them easy to machine, grind, and polish. The blend of strength, toughness, and polishability ensures that O1 bars are reliable in applications that demand precise tooling and resistance to repeated mechanical stress.

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 commonly utilized in the production of punches, dies, cutting tools, and precision molds. They excel in applications that require high wear resistance and accurate dimensional stability, such as stamping dies, plastic molds, and blanking tools. Their superb machinability allows for the crafting of intricate shapes and fine finishes, while their toughness guarantees a long service life under repeated mechanical loads. O1 steel bars are indispensable in industries where precision, durability, and consistent performance are vital for maintaining production quality.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
