1020 steel responds well to cold work and heat treating. Weldability is fair.
1020 is suitable for case hardened parts where core strength is not critical.
May also be know as LCS "low carbon steel" 1020 is no longer a stocked industry standard grade, may time A-36 and 1018 are substituted for 1020, both having low carbon contents.
