Isis Metals stands out as a top-notch supplier of premium tool steels in Manila, Philippines, proudly offering robust and high-performance **D2 Tool and Die Steel Bars** designed for precision tooling and wear-resistant tasks. D2 is an air-hardening, high-carbon, high-chromium tool steel that’s highly regarded for its remarkable wear resistance and dimensional stability. It’s a go-to choice for dies, punches, and cutting tools, excelling in long-run tooling operations. Isis Metals supplies D2 bars in a variety of sizes and conditions, ensuring dependable performance and machinability. With a commitment to quality and responsive customer service, Isis Metals is a trusted partner for toolmakers and manufacturers in demanding industrial sectors.
D2 tool steel typically features 1.50% carbon and 11.50–12.00% chromium, along with trace amounts of molybdenum, vanadium, and manganese. This unique blend results in impressive hardness (up to 60–62 HRC post-heat treatment), exceptional wear resistance, and high compressive strength. D2 boasts a tensile strength of about 2,070 MPa (300,000 psi) and maintains excellent dimensional stability during hardening. While it may not be as tough as shock-resistant steels, D2’s high chromium content offers superior corrosion resistance compared to many other tool steels. Its air-hardening characteristic reduces distortion, making it perfect for precision tools that demand accurate tolerances and a long service life.

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.
D2 Tool and Die Steel Bars find extensive use in cold work applications where high wear resistance and edge retention are essential. They are commonly employed in blanking and forming dies, stamping tools, shear blades, punches, and gauges. In the plastics sector, D2 is frequently utilized for molds and inserts, where its abrasion resistance is crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
