Abstract: The experiment on 06Cr17Ni8Mo2N austenitic stainless steel was carried out under the treatment temperature of 1000℃. After the insulation of the treated solution for 1 h, the pendulum impact test machine was utilized to carry out the impacting test on the test steel with different composition. The value of the impact energy change and the appearance of the impact fracture were analyzed, and the effects of the reduced nickel and increased nitrogen on the impact properties of the test steel were obtained. Results show that the impact energy of the test steel was brought up from 190.6 J to 247.3 J, with the impact property raised significantly.
