The results show that the diffusion rate of carbon increases due to rare earth catalysis, so the time of carburizing decreases by about 30 %, and the martensite microstructures are refined on the
20CrMo steel plate hardness:197HB. Properties of 20CrMo steel plate:20CrMo steel plate has high hardenability, no temper embrittlement, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo steel plate is a kind of low carbon steel.
