Effect of delta-ferrite on the properties of welded joints of steel 08Kh18N10T

1.	Presence in a welded joint of steel 08Kh18N10T of 2–2.5% -ferrite promotes an increase in the degree of first-order stress relaxation at 400–480°C without reducing strength properties and with retention of resistance to ICC.
2.	A reduction in the relaxation resistance of an electroslag weld with an austenitic structure with a small amount of ferrite is due to the greater deformation capacity of ferite and microvolumes of austenite adjacent to it.
