Shallow pitting/crevice corrosion in 1.4521 | X2CrMoTi18-2 | AISI 444 | S44400
| Numeric designation | 1.4521 | AISI 444 | S44400 |
|---|---|
| Chemical designation | X2CrMoTi18-22 |
| State | Shallow pitting/crevice corrosion |
| Etching | V2A-Beize @ 70 °C |
On this ferritic chromium steel, crevice corrosion took place in the form of trough-shaped corrosion attack on a pipe crimp connection of a drinking water pipeline.
High levels of chlorine were detected on the corrosion products, which were concentrated here.
