A For aluminum killed steel, subtract 3 KSI and add 1 % R/A.
For rimmed steel, subtract 5 KSI and add 2 % R/A.
For AIp and SAIP Wire under 0.200 in., add 50 psi for every 0.001 in. under 0.200 in.
NOTE 1—The values in this table have been designed to provide optimum headability and tool life in the cold forming process. The reduction of area test is not applicable to wire sizes less than 0.092 in.
