Classification
| AWS class | E 410 NiMo-15 |
|---|---|
| EN ISO class | E 13 4 B 42 |
Purpose
- High-strength martensitic Cr-Ni-Mo 12.3/4.2/0.5 basic electrode (E 410 NiMo-15) — mechanically stronger than standard INX 410 (Rm 760 MPa vs 650–800 MPa).
Why it works
Extra nickel (4.2%) over the 410 base raises the toughness of the 13% Cr martensitic steel while keeping high mechanical strength — built for parts that demand more strength than plain 410.
Fields of application
- X5CrNi 13 4 steel and its equivalent castings.
