AISI A2
A2 is an air-hardening cold work tool steel valued for its excellent combination of good toughness, dimensional stability, and wear resistance. The air-hardening characteristic minimizes distortion during heat treatment, making A2 a preferred choice for precision tooling.
A2 is an air-hardening cold work tool steel that offers an excellent balance of toughness, wear resistance, and dimensional stability. Its air-hardening characteristic minimizes distortion during heat treatment, making it a preferred choice for precision tooling where tight tolerances must be maintained. A2 achieves a working hardness of 57–62 HRC.
Compared to D-series steels, A2 provides better toughness while maintaining good wear resistance and edge retention. Its good machinability in the annealed condition, combined with predictable heat treatment response, makes A2 a versatile and cost-effective choice for medium-run production tooling across a wide range of cold work applications.
A2 tool steel is supplied in flat, square, and round bars of all standard and custom sizes.
