Abstract: PURPOSE: A heating method for carbonizing a steel with high carbon is provided to increase fitting resistance, abrasion resistance and friction resistance of the steel by forming a fine carbide inside a carbonizing layer. CONSTITUTION: A heating cycle starts carbonization of a low carbon steel under the condition of 1.2 to 2.0 of carbon concentration in an alpha + gamma area which is an Ar1 to Ar3 section. Then temperature is increased to 850 to 930°C as a target carbonizing temperature and the temperature is decreased to 800 to 850°C. An alpha phase has small carbon employment in order to be applied as a carbide nuclear generating position and to make the carbide size fine with low crystallization. The heating time is changed depending on hardening depth that takes 30 minutes to 2 hours in the alpha + gamma area, 2 to 6hours in a temperature of 850 to 930°C and 30 minutes to 1 hour in a temperature of 800 to 850°C.
