Description

Product: AISI A*6 Key words:atr hardening die steel, tool steel, die steel, specialty steel, steel bar, hotwork, coldwork, forged bar, alloy tool steel, flat bar, round bar Typical Analysis: C:0.***0.*5 Si:Max 0.*0 Mn:1.***2.*0 P:Max 0.**0 S:Max 0.**0 Cr:0.***1.*0 Mo:0.***1.*0 Ni:Max 0.*0 Advantages: 1.Air hardening from low temperature. 2. Excellent size stability in heat treatment. 3.Deep hardening. 4. Easy to machine. Availability: Moderately available, not as available as A*2. Applications: A*6 is a medium alloy steel used in die and mould applicaiton. It has a very good balance of toughness, strength and wear resistance. Quite often it is chosen because of its good machinability and non-deforming characteristics in heat treatment. Machinability: A*6 is readily machined in the annealed conditon. Its machinability is about *5% of a 1% carbon tool steel. It also has a high grindability rating. Annealing: A*6 may be annealed in either a controlled atmosphere furnace or wrapped in stainless steel foil.Heat to ***0° to ***0°F and hold approximately one hour for each inch of thickness. Cool very slowly at a rate of *0° per hour to approximately ***0°F. Annealed hardness range is normally **2 to **5 Brinell.
