FeCr
Ferro Chrome
Added to steel when the chromium level has to be adjusted without raising the carbon level. Low-carbon ferro chrome powder is also used in welding electrodes and stick electrodes.
Grades and chemistry
| Grade | Cr | Si | C | P | S |
|---|---|---|---|---|---|
| Low carbon | 6063 max | 2 | 11.5 max | 0.04 | 0.04 |
| High carbon | 60 | 4 | 68 max | 0.04 | 0.05 |
Figures are percentages. Where a grade has a ceiling, it sits beneath the value.
