1.Good combination of wear resistance and toughness.
2.Very stable in heat treatment.
3.Not difficult to machine or grind.
4.Good Hardenability.
Availability:
Readily available.
Machinability:
A-2 can be machined readily in the fully annealed condition. Its machinability rating is about 65% of a 1% carbon tool steel. It also has a high grindability rating.
Annealing:
Heat slowly to 1500° to 1600°F and furnace cool, allowing the temperature to drop about 75°F per hour to 1000°F. Then air cool. The annealed hardness is 202 to 248 Brinell.
