About A2 Tool Steel:
A2 tool steel is a versatile, air-hardening tool steel known for its excellent toughness, good wear resistance, and ability to maintain a keen edge. It has a balanced composition with approximately 1.0% carbon, 5.0% chromium, 1.0% molybdenum, and 1.0% vanadium, which contributes to its high hardness and durability after heat treatment. A2 steel is less prone to distortion during hardening compared to oil-hardening steels, making it ideal for precision tools, dies, and knives that require high stability and durability. It is widely used in applications that demand a combination of toughness and wear resistance, providing reliable performance in both industrial and cutting tool contexts.
