Classification

AWS classE 7018 - 1 H4
EN ISO classE 46 6 B 42 H5

Purpose

  • Low-hydrogen basic electrode, the highest certified-toughness step in the FERVEO STL basic range, with toughness additionally certified by CTOD (AWS E 7018-1 H4, EN ISO E 46 6 B 42 H5).

Why it works

Same mechanical-strength step as FERVEO STL 460B5, with toughness certified at the lowest temperature in the entire FERVEO STL basic range, and in this reference with toughness additionally certified by CTOD — a fracture-mechanics figure not seen on the lower steps.

Fields of application

  • Fine-grained high-strength structural-steel fabrication, safe joining of thick-section material.

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

  • Toughness certified at the lowest temperature in the entire FERVEO STL basic range, with additional CTOD certification.
  • Built for safe joining of thick-section material.

Limitations

  • The highest alloy-cost step in the FERVEO STL basic range — if that certified toughness isn't needed, the B4/B5 steps are sufficient and more economical.
