Extremely high wear resistance.
Excellent size stability in heat treatment.
Deep hardening in air.
Used for cold work tools requiring very long runs and close
tolerance. D2 has high compressive strength and is used for
blanking, stamping, and cold forming dies where emphasis is
not on toughness.
Although readily machinable in the annealed condition D2
has a lower rating than most other tool steels. It is rated
at 40% of a 1% carbon tool steel.
D2 should be surface protected duting annealing and slowly
heated to 1600°to 1650°F. Hold at temperature for one hour
per inch of thickness and then furnace cool 100°pre hour to
1000°F to below. The part may then be cooled in still air.
The annealed hardness of D2 is 212 to 248 Brinell.
