Anucha Metals, a reputable manufacturer and supplier based in Bangkok, Thailand, is dedicated to offering top-notch Tool and Die Steel D2 Bars that align with international standards. These bars are celebrated for their exceptional strength, wear resistance, and durability, making them perfect for tough industrial applications. With a strong commitment to quality assurance and ensuring customer satisfaction, Anucha Metals provides D2 steel bars tailored to the needs of the tool-making, die manufacturing, and precision engineering industries. Their products are well-regarded for their consistent performance, making them a go-to choice for sectors that demand toughness and dimensional stability.
Tool and Die Steel D2 Bars are primarily made up of high carbon and high chromium, typically featuring around 1.5–2.0% carbon and 11–13% chromium, along with trace amounts of molybdenum, vanadium, and nickel. This unique blend gives them outstanding hardness, wear resistance, and corrosion resistance. The mechanical properties include high compressive strength, excellent edge retention, and good dimensional stability during heat treatment. D2 steel strikes a balance between toughness and abrasion resistance, making it ideal for precision tools and heavy-duty dies that require a long service life even in challenging conditions.

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.
These Tool and Die Steel D2 Bars find extensive use in industries that demand high wear resistance and precise dimensions. They are perfect for crafting dies, punches, and cutting tools that need to endure repeated stress and abrasion. Common applications include shear blades, industrial knives, stamping dies, and forming tools. In the automotive and aerospace industries, D2 bars are employed in molds and precision tooling to ensure durable and efficient production. Their toughness and ability to maintain hardness even at high temperatures make them incredibly reliable for heavy-duty machinery parts and specialized engineering tasks.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
