Cold Hardened

Material condition where the mechanical properties are obtained by a cold finishing process not followed by heat treatment. NOTE 1 Cold finishing is a plastic deformation of material at a temperature below the recrystallization temperature such that permanent strain hardening occurs. NOTE 2 The percentage of cold hardening depends on the specified strength level for each material grade, as shown in Table A.3 or Table C.3 for the cold hardened condition.
