Classification

AWS classE70T-5M J
EN ISO classT 42 4 B M 3 H5

Purpose

  • Basic-type flux-cored wire, for semi-automatic or automatic welding of alloyed or unalloyed construction steel (AWS E70T-5M J, EN ISO T 42 4 B M 3 H5).

Why it works

The flux's basic character gives a soft arc with deep penetration and good bead appearance, with low-temperature impact values higher than an equivalent rutile flux-cored wire — also suited to thin sheet.

Fields of application

  • Semi-automatic or automatic welding of alloyed or unalloyed construction steel, including thin sheet, with M21 gas shielding.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.

Advantages

  • Higher low-temperature impact toughness than an equivalent rutile flux-cored wire.
  • Soft arc with deep penetration, good bead appearance, also suited to thin sheet.

Limitations

  • Restricted to flat and horizontal-fillet position — for manual welding in all positions, see the rutile range FERVEO STL 480 C/M HC FCW.
