Isis Metals, a top-notch supplier of specialty steels based in Manila, Philippines, offers premium **A2 Tool and Die Steel Bars** tailored for rigorous industrial and tooling needs. A2 steel is known for being an air-hardening, medium-alloy cold work tool steel that strikes a great balance between toughness and wear resistance. It’s a go-to choice for precision machining, mold making, and tool manufacturing. Isis Metals provides A2 bars in a variety of sizes and heat-treated conditions, catering to the specific requirements of toolmakers, fabricators, and engineering professionals. With a commitment to strict quality control and responsive service, Isis Metals guarantees dependable material performance for high-precision and high-stress applications across various industries.
A2 tool steel generally consists of 1.0% carbon, 5.0% chromium, 1.0% molybdenum, along with trace amounts of manganese and vanadium. This unique blend gives A2 a solid mix of hardness, toughness, and dimensional stability. It can be air-hardened to achieve a hardness range of 57–62 HRC with minimal distortion during the heat treatment process. A2 boasts a tensile strength of around 1,860 MPa (270,000 psi) and provides excellent compressive strength and wear resistance. Thanks to its alloying elements, it maintains edge retention and can withstand impact and abrasion, making it perfect for both forming and cutting tasks in cold work settings.

The standard annealing temperature for A2 tool and die steel bars is typically between 800°C to 850°C (1472°F to 1562°F), followed by slow cooling to relieve internal stresses and soften the material.
A2 tool and die steel bars resist corrosion through their high chromium content, forming a protective oxide layer that enhances resistance to rust and wear, especially in cold-work applications.
A2 Tool and Die Steel Bars are perfect for applications that demand high wear resistance, moderate toughness, and good dimensional stability post-heat treatment. They’re frequently utilized in cold working tools like blanking dies, forming dies, punch tools, and trimming dies. In the plastics sector, A2 is often used for injection mold components and inserts. Additionally, it’s well-suited for industrial knives, shear blades, and other wear-resistant tools.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
