    PROCESSING


    FORGING


    This alloy would be forged between 2200 and 1700ºF (1200 and 925ºC.)


    HEAT TREATMENT


    Annealing: This alloy is seldom annealed. Structures of better machinability are developed by normalizing or by isothermal transformation after forging.


    Normalizing: 1650-1700ºF (900-930ºC.)


    Carburizing: 1650-1740ºF (900-950ºC) and oil quench.


    Hardening: Core: 1560-1620ºF (850-880ºC) and oil quench. Case: 1490-1540ºF (810-840ºC) and oil quench


    Tempering: 340-410ºF (170-210ºC.)


    Machinability: The alloy is best machined in the normalized condition prior to case hardening.


    Weldability: The alloy is easily welded, but should be welded prior to case hardening.
