Impacts down to -70 C.
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.

Product Description :

Impacts down to -70 C.

  • 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 :

  • C-Mn and low alloy steel plate, pipe forgings and castings used extensively for service at cryogenic temperatures, eg: LT50.

  •  BS 1501-224 Grade 490B Plate.

  •  ASTM A333 Grade 6 Pipe.

  •  ASTM A350 Grades LF1/LF2 Forgings.

  •  ASTM A352 Grade LC2 Castings.

  • Maximum stress relief temperatures should be 620 C (for 1 hour)
