Classification

| EN ISO class | G/W 25 20 |
| Material no. (W.-Nr.) | 1.4842 |
Purpose
- Cr-Ni 25.5/20.5 solid wire for joining and surfacing heat-resistant steel — scaling-resistant to 1150°C in air and oxidizing combustion gases.
Why it works
Besides direct joining and surfacing, the manufacturer specifies it as a ductile filling layer under harder top layers within the same INX range (1.4773 and 1.4820 — the latter being FERVEO INX 312's alloy) — in other words, it buffers under a harder final overlay.
Fields of application
- Joining and surfacing of heat-resistant steel and equivalent castings.
- Ductile filling layer under harder top layers (e.g. before FERVEO INX 312).

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