Dhruv Metals, a reputable manufacturer and supplier based in Hyderabad, India, specializes in top-notch Tool and Die Steel A2 Bars, designed for high-performance tooling and various industrial applications. Renowned for their outstanding dimensional stability, wear resistance, and toughness, A2 steel bars from Dhruv Metals are crafted to meet strict standards, ensuring they can handle high stress and repeated use with ease. With a strong commitment to material integrity and precision, we cater to a wide range of industries, including manufacturing, automotive, and aerospace, providing products that comply with both national and international specifications for heat-treated tool steels.
Tool and Die Steel A2 Bars are produced from an air-hardening cold work steel that contains around 1.0% carbon, 5.0% chromium, along with smaller quantities of molybdenum, vanadium, and manganese. This unique blend strikes a perfect balance between hardness, toughness, and machinability. After heat treatment, you can expect typical mechanical properties to include a hardness range of 57–62 HRC, impressive compressive strength, and excellent dimensional stability during hardening. A2 steel tends to distort less than oil-hardening steels and offers great wear resistance, making it a go-to choice for intricate tooling and dies that require both precision and strength.

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.
Tool and Die Steel A2 Bars find extensive use in a variety of tooling and wear-resistant applications. They are commonly utilized for blanking and forming dies, punches, shear blades, mandrels, gauges, and cutting tools. A2 bars are particularly favored in manufacturing processes that involve significant impact and wear, such as stamping, forming, and plastic injection molding. Their ability to maintain a sharp edge and resist cracking under load makes them perfect for precision dies and molds. Plus, the air-hardening characteristic of A2 steel reduces dimensional changes during heat treatment, making it ideal for parts that require tight tolerances and consistent performance over long cycles.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
