Description

Product: AISI A*8 Key words:shock resistance die steel, tool steel, die steel, Alloy Construction steel, alloy structure steel, flat steel, round steel, forged steel, hotwork steel, cold work steel, steel bar, flat bar, cold bar Typical analysis: C:0.***0.*0 Si:0.***1.*0 Mn:0.***0.*0 P:Max 0.**0 S:Max 0.**0 Cr:4.***5.*0 Mo:1.***1.*5 W:1.***1.*0 Advantages: 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. Availability: Limited. Applications: 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 ****0 Rockwell C. Machinability: A*8 has a machinability rating of *5% of a 1% carbon tool steel. It also has a high grindability rating. Annealing: Heat in an atmosphere furnace to ***0°F and hold for one hour per inch of thickness. Furnace cool at *5°F per hour maximum to ***0°F then air cool. The annealed hardness of A*8 is approximately **7 to **9 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 **0° to **0°F. Doulbe tempering is recommended for best results with tempering temperatures above **0°F.
