Applications
A2 tool steel takes a place between AISI O1 and AISI D2, offering an excellent combination of good wear resistance and toughness. It may be regarded, therefore, as a“universal” cold work steel.
For cutting operations the good toughness of AISI A2 steel gives excellent resistance to chipping of the cutting edge. In many cases tools made from this A2 steel have given better tooling economy than high-carbon, high-chromium steels of the D3/ W.-Nr. 2080 type. AISI steel A2 has much better machining and grinding properties
Typical Applications for AISI/ASTM A2 steels materials: Blanking dies, block and ring gauges, coining, cold forming, cold trimming and forming dies, cold shears, rolls, knurls and knurling tools, machine parts, mandrels, punches and punch plates, reamers, shear and slitter blades, stamping dies and threading tapes.
