 Austenitic chromium-nickel stainless steels develop high strengths when cold
worked.  The following designations of cold worked tempers have been
established by the AISI for stainless steel sheet and strip:
     1/4 Hard, 1/2 Hard, 3/4 Hard, Full Hard, Extra-full Hard

 Reheating the cold worked austenitic stainless steels at temperatures below
700F increases the tensile strength.  Reheating above 800F lowers the
strength and increases the ductility.

 Cold working increases the fatigue strength of the austenitic stainless
steels.  However, the fatigue strength of these cold worked alloys is reduced
by notches, as compared to notched fatigue strength in the annealed condition.
