STUDY OF SOLUTION ANNEALING AND AGING HEAT TREATMENT ON THE MECHANICAL PROPERTIES OF X3NICRCUMOTI 27-23 STEEL

摘要

Undoubtedly heat treatment is affected on the stainless steels morphology and mechanical properties. In this study was discussed the effect of annealing and aging heat treatment cycles on X3NiCrCuMoTi 27-23 (1.4503) steel micro structure, mechanical properties and hardness. The results showed that decreasing of annealing temperatures and keeping of cycle time in specific heat treatment can be led to complex carbides precipitate in the microstructure of the 1.4503 steel and severely influences on the mechanical properties of this steel and also after increasing solution annealing time decreases the hardness of 1.4503 steel.
