Document Type and Number:
Japanese Patent JP2004244717
Kind Code:
A
Abstract:
To provide a method for producing steel for carburizing where a carburizing rate can efficiently be improved.
REM (rare earth metal)is added to steel for carburizing in which, by weight, the concentration of C is 0.1 to 0.3%. The REM concentration is controlled to 0.01 to 0.25%, and carburizing is performed at a carburizing temperature of 930 to 1,050°C.
