Semih Metals, based in Istanbul, Turkey, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Tool and Die Steel D2 Bars, catering to industries around the globe. Renowned for their precision engineering and strict adherence to international quality standards, Semih Metals delivers D2 bars that boast outstanding wear resistance, impressive hardness, and excellent dimensional stability. These Tool and Die Steel D2 Bars are crafted to perform consistently in challenging tooling applications, making them the perfect choice for industries that demand durable and long-lasting materials. With state-of-the-art production facilities and a strong dedication to quality, Semih Metals guarantees consistent performance, precise specifications, and timely delivery for customers worldwide.
The Tool and Die Steel D2 Bars are made from high-carbon, high-chromium tool steel, featuring around 1.5–2.3% carbon and 11–13% chromium, along with trace amounts of vanadium and molybdenum. This unique composition provides them with remarkable wear resistance, high hardness, and good toughness. After heat treatment, they typically exhibit a hardness of 55–62 HRC, a tensile strength ranging from 1900–2100 MPa, and excellent compressive strength. D2 steel also maintains good dimensional stability during both heat treatment and service, ensuring precision in tooling applications where accuracy and longevity are essential.

Tool and Die Steel D2 Bars can be welded, but it's challenging due to their high carbon content. Preheating, post-weld heat treatment, and using specific filler materials are essential.
Tool and Die Steel D2 Bars are semi-corrosion-resistant due to high chromium content (12%). While not fully stainless, they offer moderate resistance to rust in less aggressive environments.
Tool and Die Steel D2 Bars should be stored in a dry, ventilated area to prevent moisture exposure. Use protective coatings like oil or rust inhibitors to minimize corrosion risk.
These Tool and Die Steel D2 Bars are extensively utilized in the production of tools and dies that require exceptional wear resistance and toughness. They are particularly well-suited for creating blanking dies, forming dies, punches, shear blades, and extrusion tools. Their ability to retain hardness and resist abrasion makes them ideal for high-volume production settings. Furthermore, they find applications in the automotive, aerospace, and industrial sectors for cutting and forming tasks. Semih Metals’ Tool and Die Steel D2 Bars deliver dependable performance, extended service life, and cost-effectiveness for demanding tooling and die-making operations.
