A metallurgically based rutile flux with balanced additions of chemically basic and amphoteric minerals that deposits duplex weld metal containing some 40% delta ferrite and 60% austenite.
The flux is extruded onto a fully alloyed 29Cr 9Ni core wire using a blend of silicates that ensures both coating strength and resistance to subsequent moisture absorption.

Product Description :

  • A metallurgically based rutile flux with balanced additions of chemically basic and amphoteric minerals that deposits duplex weld metal containing some 40% delta ferrite and 60% austenite.

  • The flux is extruded onto a fully alloyed 29Cr 9Ni core wire using a blend of silicates that ensures both coating strength and resistance to subsequent

  • moisture absorption.

Welding Features Of The Electrode :

  • This unique flux formulation ensures excellent arc stability, ease of initial arc strike and re-strike, minimal spatter on AC and virtually none on DC+.

  • The resultant weld seams are smooth, evenly rippled and free from undercut while slag detachability is excellent. Metal recovery is some 103% with respect to core wire weight.

Applications And Materials To Be Welded :

  • Primarily designed for high carbon steels, cast or wrought, which are well known as difficult to weld or problem steels. The duplex microstructure of the weld metal will tolerate high dilution with such steels while still maintaining its strength

  • ductility and thus resistance to cracking. It can also be used very successfully for joining carbon steels to stainless steels, the only exception to its extensive use on such applications is that at service temperatures above 300 C a drop in weld metal ductility occurs.
