Abstract
40Cr steel diesel engine connecting rod were quenching and tempering by waste hate after forging and its mechanical properties were studied. The results showed that comparing with traditional technology, the forging-remnant-heat quenching and tempering technology route for 40Cr connecting rod of diesel engine not only meet the performance requirements of a stable product, grain refinement, as well as improve the forging of strength, hardness and toughness, but also shorten the production cycle, energy conservation, and improve labor productivity.
