Stainless steel flux-cored wires TY-E309L(Q)

Cracking susceptibility of low resistance to intergranular corrosion can be good.
TY-E309L(Q)
Standard:
GB/T17853-1999 E309LT1-1, AWS A5.22-1995 E309LTI-1
Introduction:
this is ultra-low carbon stainless flux-cored wires, applicable to weld 24%Cr-13%Ni stainless steel. Because of low carbon, It can effectively prevent the intergranular corrosion without stable elements Nb and Ti,its crack sensitivity is low.
Application:
It is usually used in the same type of stainless steel welding, or welding composite steel and dissimilar steel, wall transition layer and components of nuclear reactor pressure vessel.
