* Annealed S = 5,100psi, Hard Drawn S = 11,300psi, for sizes ¼" to 2½" Nominal. S = 8,700psi for sizes over 2½" Nominal, as these sizes are not normally available in the annealed form and are not therefore covered by ASME.
The figures provided are for guidance only, based on the indicated temperatures.
