Key Features
- High purity: Ensures minimal contamination of critical steel grades
- Fast dissolution: Fine powder integrates quickly into melt, shortening alloying time
- Dark silver appearance: Indicates high metallic content and low oxide surface
Benefits in Premium Alloy Steel Production
- Enables tight control of silicon levels for electrical steels, tool steels, and stainless grades
- Improves magnetic permeability and electrical resistivity in grain-oriented electrical steels
- Enhances wear resistance and red-hot strength in tool and die steels
Applications
- Vacuum induction melting (VIM) for aerospace and bearing steels
- Production of high-performance electrical steels for transformers and motors
- Ladle additions in specialty steel programs requiring exact chemistry
