Steels with UTS 800N/mm2
The design emphasis of the chemically basic flux is engineered to ensure the
optimum weld metal properties demanded by the specification are fully met.
The basic flux containing the appropriate alloying elements with a controlled
balanced addition of iron power, is extruded onto a high purity ferritic core wire
with a blend of silicates that ensures both coating strength and a coating resistant
to subsequent moisture absorption.

Product Description :

Steels with UTS 800N/mm2

  • The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met.

  • The basic flux containing the appropriate alloying elements but minimal iron powder, is extruded onto a high purity ferritic core wire and bound with a blend of silicates that ensure both coating strength and a coating resistant to subsequent moisture absorption.

Welding Features Of The Electrode :

  • The chemical nature of the flux together with a significant proportion of iron powder ensures maximum deposition efficiency without detracting from its ability to be used in all positions except vertical down.

  • Overall the arc is very stable, slag detachability is good and metal recovery is some 115% with respect to the core wire.

Applications And Materials To Be Welded :

  • This electrode is typically used for welding of general structural steel fabrication in high strength low-alloyed steels, which may be used for cranes, earth moving equipment, and other highly stressed structural components.

  • However, hydrogen release heat treatment is often applied at 250C for 1 hour per 15cms of plate thickness and this in combination with 150C minimum preheat ensures the integrity of the HAZ areas.
