23CrNi3Mo has advantages such as surface hardness, extremely high wear resistance, fatigue resistance and bending fatigue strength, and the price is more than twice that of 55SiMnMO, 60Si2Mn and other materials.
Rock drilling tool material: At present, the materials of domestic rock drilling rods are 23CrNi3Mo, 55SiMnMO, and 60Si2Mn.
Among them, the main materials of light rock drilling tools are 55SiMnMO and 60Si2Mn. As the impact energy and drilling hole diameter increase, heavy rock drilling tools should be processed with 23CrNi3Mo material.
Compared with 55, 23CrNi3Mo has advantages such as surface hardness, extremely high wear resistance, fatigue resistance and bending fatigue strength, and the price is more than twice that of 55SiMnMO, 60Si2Mn and other materials.
