Effect of Tube Spinning With Subsequent Heat-Treatment on Performance and Microstructure Evolution of T250 Maraging Steel

HU Zheng-fei , WANG Chun-xu

钢铁研究学报(英文版)

The effects of spinning deformation and subsequent heat treatments on the mechanical properties and microstructure of 18Ni Co-free Maraging steel (T250) tube were evaluated comparatively with the perform. An obvious radial shrinkage is detected in spun tubes after heat treatment and the magnitude of...

LIU Yu-rong , YE Dong , YONG Qi-long , SU Jie , ZHAO Kun-yu , JIANG Wen

钢铁研究学报(英文版)

The microstructures and mechanical properties of Cr13 super martensitic stainless steel after different heat treatments were studied. The results show that the structures of the steel after quenching are of lath martensite mixed with a small amount of retained austenite. With the raising quenching t...
