Mechanical Properties of 3Cr24Ni7SiNRE Welded Joint

The mechanical properties of 3Cr24Ni7SiNRE are experimentally studied, based on which the focus is laid on the discussion of normal and high-temperature mechanical properties of the welded joint with various welding technology. Especially the relationship between the macro-mechanical properties and the microstructure is analysed, some conclusions are obtanied and some qusetions of application which must be payed attention to are pointed out.
