FCAW for 22%Cr-12%Ni Stainless steel
Characteristic
(1) CSF-309L(P) is flux cored wire and designed for Fillet & H-F(All-position) welding with CO2
gas Shielding.
(2) It provides the excellent usability with stable arc, less spattering, good bead appearance, better
slag removal, and less quantity of welding fume comparable to solid wire.
(3) Is containing Ferrite of a reasonable quantity and crack-resistance, integranular corrosion
resistance, mechanical properties of weld metal is superior.
(4) Shield gas is 100%CO2 or Ar+CO2 gas.
Applications
CSF-309L(P) is suitable for welding of 22%Cr-12%Ni steel and heat resistant steel and dissimilar
joint such as a stainless steel to carbon steel of low alloy steel. Under layer welding on cladding steel or stainless steel.
Notes on Usage:
(1) The optimum flow of CO2 for Shielding is 20~25ℓ/min.
(2) Protect the weld with a screen to prevent blowholes caused by wind where the wind velocity is
2m/sec and more.
(3) Keep the distance between tip & base metal at 15~25mm.
