Cast Steel – For General & Specialized Applications
Steel castings provide superior strength, wear resistance, and are ideal for high-stress environments. Used across automotive, machinery, and construction sectors.
Examples:
- GS 38 (GE200) | 1.0420 | Yield: 200 MPa | Rm: 380 MPa | Elongation: 25%
- GS 60 (GE300) | 1.0558 | Yield: 300 MPa | Rm: 600 MPa | Elongation: 15%
- GC45 | 1.0503 | High load parts for motor, machine & automotive applications
Hardened Cast Iron (Hard Cast Iron)
Our hard cast iron alloys provide excellent abrasion resistance, even under impact stress. Typical applications include:
- Liner plates
- Mixer blades
- Pump housings
| Grade | Material No. | Hardness as Cast [HRc] | Hardened [HRc] | Application |
|---|---|---|---|---|
| GJN-HV600 (XCr14) | EN-JN2060 | ~35 – 45 | 55 – 63 | Abrasion with moderate impact |
| G-X280CrMo15 | 0.9635 | ~45 – 55 | 60 – 65 | High toughness, wear-resistant parts |
| G-X210Cr12 | 1.2080 | ~250 HB (annealed), 60–64 HRc (hardened) | For stamping, drawing dies |
Special Alloys & Heat-Treated Steels
We also cast high-strength alloy steels for demanding mechanical properties such as:
- G30CrNiMo8 (1.6580): Up to 1450 MPa tensile strength
- G50CrMo4 (1.7228): Excellent impact and fatigue strength
- G17CrMo9-10 (1.7379): Creep resistance for high-temp use
Additional Materials
Upon request, we also offer:
- Austenitic manganese steel casting (GX120Mn13)
- High chromium cast iron (wear resisting aplications)
- Customer-specific alloys
Notes on Mechanical Data
All mechanical values are based on separately cast test bars and should be considered as reference values only. Properties may vary depending on wall thickness, heat treatment, and casting geometry.
