Stainless steel flux-cored wires TY-E347L(Q)

Cracking susceptibility of low resistance to intergranular corrosion can be good.
TY-E347L(Q)
Standard
:
GB/T17853-1999 E347LT1-1, AWS A5.22-1995 E347LTI-1
Introduction
:
this is ultra-low carbon stainless flux-cored wires, applicable to weld 19%Cr-11%Ni-Ti stainless steel. Because of low carbon, It can effectively prevent the intergranular corrosion with stable element Nb and its crack sensitivity is low.
Application
:
It is usually used in Petro-Chemical equipment and pressure vessels of corrosion-resistant stainless steel, such as welding stainless steel of 19%Cr-11%Ni-Nb and 19%Cr-11%Ni-Ti.
