A2 Tool Steel Hardened & Ground Round
A2 tool steel hardened and ground round is an air hardening, cold work, chromium alloy die steel that is preferable to O1 tool steel in applications requiring greater size stability, machinability and safer hardening. The wear resistance properties and cost place A2 between that of O1 and D2 tool steel making it a good all purpose grade for many applications. The increased wear resistance and lower distortion make A2 tool steel particularly useful in longer production runs on either light or heavy gauge stock. Applications include: blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts. Common trade names include
Air-True, Windsor, Airkool, AL4, Select B, Thyrodur 2363, Airque, Sagamore, Cromo-Loy, EZ-DIE, A-H5.
