Abstract
PURPOSE: To manufacture a steel having superior machinability and giving shavings easy to treat with a small quantity of heat by holding a steel at a temp. of the Ar3 point W the Ar1 point for a fixed time directly from a temp. zone above the Ar3 point or during the cooling and by cooling the steel at a controlled cooling rate.
CONSTITUTION: A steel is held at a temp. of the Ar3 point W the Ar1 point for a fixed time directly from a temp. zone above the Ar3 point or during the cooling. The steel is then cooled at a controlled cooling rate to produce 5W80% martensite phase in the steel, and it is tempered if necessary to manufacture a steel with superior machinability. By this method after-heat-treatment can be eliminated after cutting in case of certain cut parts, so a dimensional change due to the treatment can be prevented.
