GJS 450 is a type of ductile iron characterized by its good mechanical properties, which primarily include a minimum yield strength of 450 MPa. The "GJS" stands for "Gusseisen mit duktiler Struktur" in German, meaning "cast iron with ductile structure," and the "450" designates its minimum tensile strength.
### Key Features of GJS 450 Material:
1. **Composition**:
- It typically contains a high carbon content (around 3-4%) and silicon
