Conclusions
-
1.
Presence of bcc phase in sheet steel 18Kh15N5AM3 gives rise to embrittlement after annealing at temperatures of about 400°C. The austenitic structure of the steel realized in wire provides a higher thermal stability of mechanical properties compared with the twophase condition.
-
2.
Intense loss of strength for steel 18Kh15N5AM3 occurs after annealing at temperatures above 550°C.
