Continuous cast iron hollow bar:
----High Density----Zero Defects ----Superb Wear Resistance ----Fatigue Strength----High Purity----Corrosion Resistance ----Excellent Machinability---Vibration Damping...

By far, we could supply the continuous cast iron hollow bars as follow:
1. Ductile Cast Iron Pipe/bar(ISO: 400-18/500-7/600-3/700-2/800-1)
---spheroidization rate 1~2, ball diameter 7~8, ball number 400~600/mm2
---compare sand casting, at same strength, elongation increase 50~100%
2. ADI(Austempered Ductile Iron)
---σb≥ 1200 mpa, δ ≥ 2%, ak≥ 35J/mm2
3. Gray Cast Iron Pipe/bar(ISO: 150/200/250/300/350)
---Matrix: Ferrite+pearlite
---σb=150-350 Mpa, HB=150-240, E=1.1-1.7*105Mpa
4. Alloy Gray Cast Iron Pipe/bar
--CrNiMo Cast Iron--CrMoCu Cast Iron
--High Nb Cast Iron--High Ni Cast Iron...
5. Specification:
---Cross-Section: Round, Rectangle, Elliptic, Hexagonal
---OD: 60-320mm, Thickness: 8-35mm
Our material could be widely used in hydraulic, pneumatic, auto, machine tool, locomotive spare parts, especially the continuous cast ductile iron possess strength of steel but also has advantage of cast iron, very appropriate for precise manufacturing.
