Excellent size stability in heat treatment. Deep hardening in air. 3.die steel 1.***9, D2 AVAILABILITY Readily available *0~**0mm flats:*0~**0x*0~**0mm 4.die steel 1.***9, D2 APPLICATIONS Used for cold work tools requiring very long runs and close tolerances. D*2 has high compressive strength and is used for blanking, stamping, and cold forming dies where emphasis is not on toughness. Some other applications are slitters, punches, thread rolling dies and trim dies. 5.die steel 1.***9, D2 MACHINABILITY Although readily machinable in the annealed condition D*2 has a lower rating than most other tool steels. It is rated at *0% of a 1% carbon tool steel. It also has a low to medium grindability rating. 6.die steel 1.***9, D2 ANNEALING D*2 should be surface protected during annealing and slowly heated to ***0� to ***0�F. Hold at temperature for one hour per inch of thickness and then furnace cool **0� per hour to ***0�F or below. The part may then be cooled in still air. The annealed hardness of D*2 is **2 to **8 Brinell.
