Material Notes:

Airdi 150 (AISI D2) is an air-hardening, high carbon, high chromium tool steel, heat treatable to HRC 60-62. It offers excellent abrasion resistance, due to a large volume of carbides in the microstructure. Airdi 150 (D2) has been widely used for many years in cold work applications requiring very high wear resistance. It is machinable in the annealed condition and, like other air-hardening tool steels, exhibits minimal distortion on hardening.Information provided by Crucible Specialty Metals.
