3.1
normalizing rolling
rolling process in which final deformation is carried out in a certain temperature range leading to a material
condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are
retained even after normalizing
NOTE The symbol for this delivery condition and for the normalized condition is N.
