This is beneficial for improving wear resistance and resistance to plastic deformation. When tempered at 300-400\u00b0C, the hardness can be maintained at around 60 HRC, exhibiting good wear resistance and toughness. However, this steel is prone to decarburization, and measures should be taken to prevent oxidative decarburization during quench heating. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mechanical
