|---|---|
| EN ISO class | ZX9CrNiSiNCe21-11-2 |
| Material no. (W.-Nr.) | 1.4835 |
Purpose
- Special Cr-Ni-Si-N (21/10) TIG rod designed for welding Outokumpu 253 MA-type heat-resistant steel — scaling-resistant to 1150°C in air.
Why it works
Corrosion resistance is excellent AT HIGH TEMPERATURE, but the manufacturer warns it is NOT intended for wet corrosion — a specialized grade for hot air service, not aqueous environments.
Fields of application
- DIN 1.4818, 1.4835 (253 MA-type heat-resistant steel).
