Aviation stainless steel 0Cr17Ni4Cu4Nb has excellent properties and is widely used in important parts of various machinery. The equivalent static compression test and impact test of 0Cr17Ni4Cu4Nb aviation Martensitic stainless steel at normal temperature were followed out by a universal test machine (UTM5305) and a high temperature separation Hopkinson test facility, respectively. The equivalent static compression data of 0.001, 0.01 and 0.1 s-1 at 25°C and the dynamic stress-strain data of 25, 350, 500 and 650°C at 25°C and the authors got strain rates of 750, 1500, 2000, 2600, 3500 and 4500. According to them, a Johnson Cook (JC) modified constitutive model was built and its prediction accuracy was confirmed. The consequences indicate that the correlation of association (R) is 0.987513 and mean relative error (AARE) of the revised JC constitutive equation is 0.51%, which indicate that the revised JC constitutive equation is a little accurate and reliable. When they are in high strain rates, generally speaking, they can predict its stress-strain connection.
