    Abstract: Stanadyne Case 239 COLD DRAWN FREE-MACHINING RESULFURIZED AND REPHOSPHORIZED STEEL BARS HAVING CONTROLLED MECHANICAL PROPERTIES AND CONTROLLED MACHINABILITY A cold drawn resulfurized and rephosphorized freemachining steel bar has the composition, by weight, C up to 0.08%; Mn 0.6% to 1.4%; Si up to 0.1%; P at least 0.03%; S 0.25% to 0.50%; Cb 0.01% to 0.10%; V up to 0.1%; the sum of Ni, Cr, Mo, and Cu up to 0.15%; balance iron. The ratio of %Mn / %S is from 1.6 to 4.0, and the ratio of (%Mn - 1.62 X %S) / %Cb is from 2 to 50. The yield strength of the steel bar is further determined by the draft in cold drawing the bar from the hot rolled state and the size and cross section of the bar after draft.

    Abstract: A cold drawn free-machining steel bar having a composition consisting essentially of, in weight percent, C up to 0.15; Mn 0.7 to 1.3; P 0.03 to 0.09; S 0.30 to 0.50; Bi 0.05 to 0.25; the sum of Ni, Cr, Mo and Cu up to 0.15 and the balance iron. The ratio % Mn / %S is from 1.7 to 3.0 and the %Mn-1.62x%S is from 0.05 to 0.40. The ratio %Bi /(%Ni+%Cu) is at least 2.0. The yield strength of the steel bar is further determined by the draft in cold drawing the bar from the hot rolled state and the cross section of the bar prior to draft.
