| Abstract: | The mechanical properties of martensitic precipitation hardened stainless steel 0Cr17Ni4Cu4Nb in ambient temperature and in cryogenic temperature separately under the specified heat treatment state are surveyed by performance test both for steel used for test and steel used for comparison.The paper points out that the effective way to get optimal cryogenic properties for 0Cr17Ni4Cu4Nb is that solution and double aging treatment must be done for the material.In conclution,the stainless steel 0Cr17Ni4Cu4Nb has priority over other materials when selecting them for making the main shaft of a cryogenic liquid pump. |
