4E Cast Iron


Kormax 4E Continuous Cast Iron bars consist of a uniform pearlitic structure from surface to core. As a continuous cast iron bar it has a fine grain structure combined with the fine graphite flake size and dense homogeneous structure. The material is well suited for high speed machining and is suitable in applications that demand the ability to withstand high pressures without leaking.

3D and 4E Cast Iron

3D Ductile Cast Iron

3D Cast Iron is a ductile iron that has a stock grade of 3D and is otherwise known as spheroidal graphite or nodular iron. The material is high strength ductile and more readily machined than other styles of cast iron. Its properties include being highly elastic and resistant to impact and is suitable for applications involving thermal and mechanical shock. 3D Ductile Iron is also the preferred choice for making hydraulic cylinder components.
