What is A2 Tool Steel?

A2 tool steel is a versatile, air-hardening, cold-work tool steel belonging to the "A" group of tool steels. It is characterized by its excellent combination of wear resistance and toughness, making it a preferred material for a wide range of tooling applications. Positioned between O1 (oil-hardening) and D2 (high-carbon, high-chromium) tool steels, A2 offers a superior balance of properties. Its 5% chromium content provides good hardenability and dimensional stability during heat treatment, a critical factor for complex and precision components.

The key advantage of A2 steel is its simple, low-temperature heat treatment and minimal distortion, which reduces manufacturing costs and lead times. Its reliable performance and durability make it a standard choice for medium-run stamping and forming dies, gauges, and cutting tools where a balance between hardness and toughness is essential.
