Ferro Silicon Zirconium
SPECIFICATION
- Zr : 15% min. Si : 38% min
Properties and Application
- Zirconium is one of the most reactive elements that forms stable compounds with oxygen, nitrogen, sulphur and carbon.
- It is also used as a de-oxidant to modify non-metallic inclusions and also fixes uncombined nitrogen in boron steels particularly.
- FeSiZr is used to scavenge impurities (Oxygen, Nitrogen, Sulphur).
- In high alloys steels, Zirconium increases hardness but decreases ductility.
- In stainless steels, Zirconium retards the formation of sigma phase
