New Breakthrough: EN-GJS-800-2 (QT800-2) Nodular Casting Part Successfully Delivered
Nodular casting parts are widely used across industries, including machinery, automotive, mining, and construction. However, producing EN-GJS-800-2 (QT800-2)—a high-strength ductile iron—is extremely challenging, with very few foundries capable of achieving the required specifications.
Chemical Composition:
C: 3.5–3.9% | Si: 2.2–2.8% | Mn: 0.5–0.8%
Mg: 0.03–0.06% | Rare Earth: 0.02–0.04%
Mechanical Properties:
Tensile Strength: >800 MPa
Yield Strength: >480 MPa
Elongation: >2%
A European customer previously manufactured this part locally but was forced to seek alternative suppliers after their foundry closed. Despite testing multiple suppliers worldwide, they faced high costs and inconsistent quality—until partnering with us.
Our Solution Delivered:
✅ Superior Quality – Meeting strict material and performance standards
✅ Cost Savings – 30% lower than the customer’s original production cost
This successful delivery highlights our expertise in high-performance casting solutions, reinforcing our ability to meet even the most demanding industry requirements.
