| EN ISO class | E 18 9 MnMo B 22 |
Purpose
- Basic-coated Cr-Ni-Mn-Mo electrode (19% Cr · 9.5% Ni · 1% Mo · 4% Mn), developed specifically for welding armor steel and hot-work tool steel.
Why it works
Adds molybdenum (1%) to the 307-family base — built for the toughest case: joining hard-to-source steels, armor plate and tool steels, on top of the general Cr-Ni stainless and high-strength steel use.
Fields of application
- Welding of armor steel and hot-work tool steel.
- Joining of hard-to-source steels, Cr and Cr-Ni stainless steels, and high-strength steels.

Advantages
- Additional molybdenum (1%) versus INX 307 B/R.
Limitations
- The deposit work-hardens due to its manganese content (4%) — machine before it hardens.
