Effect of Mn content in medium Carbon steel

  1. Aug 2, 2006 #1
    Hi guys,

    I need to find material compatibility to carbon steel AISI 1045 that is available locally. The closest that I can find is the SWRH 42A. All of the chemical composition matches (C, Si, P, S), except for Mn.
    AISI 1045 has Mn content of 0.60 - 0.90, while SWRCH 42A has Mn content of 0.30 - 0.60.
    This material will be subjected to cold heading process (with or without annealing process), and then heat treated (quenched and tempered) to final hardness of HRC-30.

    So, the question is, what does the difference in Mn content will affect me?
    Will it affect the hardness/tensile strength/ductility?
