Kanish Metals is one of the prominent manufacturers and suppliers of Tool and Die Steel O1 bars in Dubai, UAE, providing top-quality, multi-purpose steel products to ensure maximum machinability and durability. O1 steel bars have extensive applications in tool making and die industries where accuracy, hardness, and machinability are of key importance. Kanish Metals guarantees each batch to international standards of mechanical properties, dimensional precision, and consistency of heat treatment. Kanish Metals supplies the automotive, aerospace, and manufacturing industries with consistent O1 steel bars on time and with excellent customer service.
Tool and Die Steel O1 bars are composed of oil-hardening, high-carbon steel with about 0.9–1.0% carbon with chromium, manganese, and tungsten as additions. This alloy offers good resistance to wear, toughness, and good machinability in its annealed state. O1 steel bars can be hardened to obtain hardness up to 60 HRC with excellent dimensional stability. Their ease of machining and polishing makes them suitable for the manufacture of accurate tools and dies that require sharp cutting edges and close tolerances.

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.
Tool and Die Steel O1 bars find widespread use in applications that demand a combination of hardness, wear resistance, and machinability. They are best suited for making cutting tools, punches, dies, shear blades, and forming tools. The automobile and aerospace sectors use O1 steel bars for tooling where accuracy and toughness are needed under moderate stress. These bars are also employed in stamping, metal forming, and general-purpose tooling where ease of machinability and stable hardness are critical. O1 steel bars exhibit reliable, long life performance in many tool and die applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
