Product Description
Spheroidal Graphite (Nodular) Roll is also called Ductile Iron rolls. It is available in customized chemical compositions, specification and hardness to cater to the needs of different applications. This can be designed in different structures from Ferrito-Pearlitic to Bainitic & Martensitic having varied carbide graphite and contents. For ensuring higher strength of the Spheroidal Graphite (Nodular) Roll, it is heat treated. This is widely used in different applications from slabbing and blooming mills, finishing of wire rod, strip mill, etc. It is also used in rail and structural mill.
