Classification
| AWS class | E 410NiMo-25 |
|---|---|
| EN ISO class | E 13 4 B 62 |
Purpose
- Higher-strength variant of INX 410MoNiMo — Rm 800–980 MPa, the strongest of the entire 410 martensitic family.
Why it works
Same Cr-Ni-Mo principle as INX 410MoNiMo B, with slightly less chromium and slightly more nickel — the result is markedly higher mechanical strength (Rm 800–980 MPa vs the B variant's 760 MPa).
Fields of application
- X5CrNi 13 4 steel and its equivalent castings, in parts under higher mechanical demand.
