Bohler-Uddeholm AISI A2 Cold Work Tool Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Tool Steel; Cold Work Steel

Material Notes: Description: AISI A2 is an air- or oil hardening chromiummolybdenum-vanadium alloyed tool steel characterized by

AISI A2 is characterized by:

  • Good machinability
  • High stability after hardening
  • High compressive strength
  • Good hardenability
  • Good wear resistance

Applications: AISI A2 takes a place in the Uddeholm tool steel range 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 gives excellent resistance to chipping of the cutting edge. In many cases tools made from this steel have given better tooling economy than high-carbon, high-chromium steels of the D3/W.-Nr. 2080 type. AISI A2 has much better machining and grinding properties.

Key Words: AISI A2; W.-Nr. 1.2363
