The flux cored wire for quarter-phase stainless steel welding which makes the solidification crystal grain minute

摘要

This invention is something which offers the flux cored wire for quarter-phase stainless steel welding which refines the solidification crystal grain in order to obtain the weld metal where characteristic and ductility are superior, the mass for wire all mass as the chemical composition which is contained in the crust and the flux, % with, C: 0.001 - 0.1%, Si: 0.01 - 1.0%, Mn: 2.0 - 6.0%, Cr: 17.0 - 27.0%, Ni: 1.0 - 10.0%, Mo: 0.1 - 3.0%, Al: 0.002 - 0.05%, Mg: 0.0005 - 0.01%, Ti: 0.001 - 0.5%, N: To contain 0.10 - 0.30%, furthermore, P: 0.03% or less, S: It restricts 0.01%, or less at the same time, 0.73 Cr equivalent Ni equivalent 4.0 and Ti (mass %) N (mass %) it fills up the 0.0004, it features that the remainder consists of the iron and the inevitable impurity.
