The Effect of Nb+Ti on the Martensite Fraction in Ferritic Stainless Steel Sheet during Welding Process

Abstract:

In this paper, the welding microstructure of Ferritic Stainless Steel sheet with different Ti, Nb elements were studied. The experiment results shows that the addition of alloying element Ti +Nb stabilization steel causes the precipitation of Nb(CN) and TiN. This can reduce the C content, so the temperature of Ac1 increases, then it would be difficult to get martensite. Due to Martensite is harmful for toughness, so Ti+Nb elements are in need.
