Heat Treatment Of Steel






Category: HEAT TREATMENT OF STEEL

Heat treatment consists in heating and cooling metal at definite
rates in order to change its physical condition. Many objects may
be attained by correct heat treatment, but nothing much can be
expected unless the man who directs the operations knows what is
the essential difference in a piece of steel at room temperature
and at a red heat, other than the obvious fact that it is hot. The
science of metallography has been developed in the past 25 years,
and aided by precise methods of measuring temperature, has done
much to systematize the information which we possess on metallic
alloys, and steel in particular.
