Microstructure and mechanical properties of Cr9Mo tube after long time service at high temperature

摘要：

The Cr9Mo seamless alloy steel tubes,which served for about 130000 hours are investigated experimentally. The research involves optical metallographic examination,tensile test,creep test,etc. The degradation of the properties of the Cr9Mo steel after long time service has been discussed and the residual life of the tube in terms of the damage of the structure is estimated.
