We cater to a variety of industrial sectors, delivering high-quality steel products that stand out for their durability, precision, and exceptional performance in tool-making and die applications. By strictly following international quality standards, we guarantee consistent product reliability and keep our customers satisfied. At Anucha Metals, we’re dedicated to offering cost-effective solutions, making us a trusted partner for industries that need precision-engineered Tool and Die Steel A2 Bars for their demanding applications.
Tool and Die Steel A2 Bars are air-hardening tool steels primarily made up of carbon (1.0%), chromium (5%), along with molybdenum, manganese, and vanadium. This unique blend gives them remarkable wear resistance, toughness, and dimensional stability during heat treatment. On the mechanical side, A2 bars boast a Rockwell hardness of 57–62 HRC, along with impressive compressive strength and moderate impact resistance. Their well-balanced properties make them perfect for heavy-duty tooling, enhancing performance, machinability, and resistance to deformation even under high-stress conditions.

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 should be stored in a dry, cool environment, away from moisture and corrosive elements. Ensure proper ventilation and avoid direct contact with the ground to prevent rust.
These A2 Bars are widely utilized across various industries for crafting precision dies, punches, cutting tools, and forming tools. Their outstanding wear resistance and toughness make them particularly suited for cold work applications like blanking, shearing, and stamping. Additionally, they are commonly used in the production of molds, gauges, knives, and industrial machine components that demand strength and durability. Thanks to their ability to maintain hardness and stability under high-stress situations, A2 bars are the go-to choice in manufacturing, automotive, aerospace, and engineering sectors for creating tools that last.
