A2 (1.2363) is a common, general purpose grade of tool steel, used to make tools for shaping metal, wood & other such materials. It is a medium alloyed, air hardening cold work tool steel with 1% carbon, 5% chromium, giving high hardness, good dimensional stability, excellent compressive strength, and good toughness after heat treatment. The wear resistant properties are however intermediate, better than 01 but not as great as in high carbon, high chromium steels such as D2 & D3. The upside is however that it is easier to machine and grind.
