0Cr13Ni8Mo2Al Experimental Study on High and Low Temperature Properties of Material
The mechanical properties of 0Cr13Ni8Mo2Al steel at room temperature,high temperature(300℃)and low temperature(-55℃),thermal expansion coefficient at-55℃～300℃,and the finished nut made of 0Cr13Ni8Mo2Al material at room temperature,high temperature(300℃)and low temperature(-55℃)were tested by sampling after aging.The performance data at different temperatures were obtained by axial failure load test.The results showed that the performance of 0Cr13Ni8Mo2Al decreases at high temperature,and the strength increases obviously at low temperature,but the toughness decreases and the plasticity deteriorates.It provides important reference value for the application of 0Cr13Ni8Mo2Al material for aerospace standard parts.
