Crucible AIRKOOL® (AISI A2) Tool Steel
Subcategory: Tool Steel; Air-Hardening Steel; Medium Alloy Steel; Metal
Close Analogs: Composition: Iron content calculated as remainder
Material Notes: Airkool (AISI A2) is an air-hardening medium alloy tool steel which is heat treatable to HRC 60-62. It has wear resistance intermediate between the oil hardening tool steels (O1) and the high carbon chromium tool steels (D2). Because it offers a combination of good toughness along with moderate wear resistance, it has been widely used for many years in variety of cold work applications which require fairly high abrasion resistance but where the higher carbon/ high chromium steels are prone to chipping and cracking. Airkool is quite easily machined in the annealed condition and, like other air-hardening tool steels, exhibits minimal distortion on hardening, making it an excellent choice for dies of complicated design.Information provided by Crucible Specialty Metals.
