| Abstract: | Targeting 20Cr2Ni4,17CrNiMo6,18CrNi8 steels commonly used for heavy duty gears both at home and abroad, contrast tests of structural inheritance removal of forging stocks after pre - heat - treatment, carburizing speeds and internal oxidation inclinations are conducted. Testing results show that conventional pre - heat - treatment is effective to the refinement of forging structures of these 3 kinds of steels, while 20Cr2Ni4 steel indicates the slowest carburizing speed, 18CrNi8 steel shows the strongest internal oxidation tendency, and 17CrNiMo6 proves to be the best optional material. |
