  AISI 4142 FORGINGS
  AISI 4142 grade alloy steel is forged at a temperature of around 2150ºF (1175ºC) and could be forged down to a temperature of approximately 1700ºF (925ºC). The alloy may be slow cooled after forging or transferred to a furnace held at what may be the finish forging temperature. Such a treatment would in fact amount to a type of annealing treatment.
   
  FORGING APPLICATIONS
  This alloy steel is used for applications as diverse as bending dies and die holders, together with forged gears, flanges, collets, arbors, spindles, axles, clutch parts, forming rolls and various machine tool components.
   
  HEAT TREATMENT
  Annealing: For optimum machinability this grade of steel should be annealed to a structure of coarse pearlite to coarse spheroidite. The steel should be austenitized at 1550ºF (845ºC) and cooled to 1390ºF (755ºC) at 25ºF (14ºF) per hour prior to air cooling, or alternately cooled from the austenitizing temperature to 1250ºF (675ºC) and held for 5 hours, for an iso-anneal.
   
  Normalizing: This steel is normalized at 1600ºF (870ºC) followed by air cooling.
   
  Hardening: The steel will be austenitized at 1550 – 1600ºF (845 – 870ºC) followed by water or oil quenching, depending upon size and intricacy of section.
   
  Tempering: The steel will be tempered at a temperature previously known to give the required mechanical properties for the section size and intricacy in question.
   
  Machinability: This grade is readily machinable following a heat treatment that will give the structure required for optimum machinability.
