FCW Sub 904LG
Metal cored stainless steel wire for gas shielded arc welding
Beschrijvingen & toepassingen
· Metal cored stainless steel wire for gas shielded arc welding
· 20% chromium - 25% nickel - 5% molybdenum - 1,5% copper - low carbon deposit
· Enhanced productivity, improved weldability, better wetting properties compared to solid wires
· Excellent weld metal quality and X-ray soundness
· High welding speeds are possible in the horizontal position
APPLICATIONS
FCW Sub 904LG is suitable for welding stainless steels of similar composition and for dissimilar welds between these steels and mild, low alloy and other stainless steels. It is an alternative choice to overmatch leaner alloys such as 317LN, 1.4439 etc.
