1.The most versatile cold work die steel. More toughness than A-2 or D-2. More wear resistance than S-7.
2.Very stable in heat treatment.
A-8 combines good/wearing qualities with excellent toughness characteritics. It is well suited for many metal working dies and punches which operate in the hardness range of 55-60 Rockwell C.
A-8 has a machinability rating of 85% of a 1% carbon tool steel. It also has a high grindability rating.
Heat in an atmosphere furnace to 1550°F and hold for one hour per inch of thickness. Furnace cool at 25°F per hour maximum to 1000°F then air cool. The annealed hardness of A-8 is approximately 197 to 229 Brinell. Allow to heat slowly to the desired temperature and hold for a period of two hours. Remove from furnace and cool in still air. For most cold work applications tempering should be carried out in the range of 300° to 600°F. Doulbe tempering is recommended for best results with tempering temperatures above 600°F.
