| Abstract: | The bars and heavy gear ring blanks of 31CrMoV9 steel were solution-double-refinement treated. The results show that 70-mm-diam bar can be through hardened, and after high tempering the size class number of the tempered sorbite is 1, and the grain size number is 6.5 to 7.5, the mechanical properties reaching or exceeding those in the Germany standards, and removing cutting ability problem of vanadium-containing steel. |
