Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    The hardenability and strength properties of continuously cast billets of 30KhGT steel meet the requirements of GOST 4543-71. The characteristics of plasticity and impact strength were below these requirements even after rolling with a reduction of λ=6.24.

  2. 2.

    After drop forging of an experimental lot of billets for ZIL-130 automobile rear axle driven gears from continuously cast billets of 30KhGT steel first rolled with a reduction of λ=1.48 the macrostructure was satisfactory and the combination of mechanical properties was sufficiently high. Therefore, drop forging may be recommended for wider production testing.
