Alloyd Rolls

Rolls of specific metallurgical composition may not be readily available. Most iron foundries would be happy to quote on your specific requirements.

The spheroidal graphite and pearlite matrix you mention are the result of the casting and heat treating process.

When getting quotes it pays to get at least 3. You learn a lot in the process and achieve a lower price when they know you are shopping around.

Cast Pearlite iron of Spheroidal graphite , Ni & Mo alloyed...

Spheroidal graphite is the clue that you are looking for a DUCTILE CAST IRON. This is also called nodular cast iron. The 'Nickel and Moly alloyed' can be added in smaller quantities to to ductile cast Irons to achieve high strength or attainment of mechanical properties in heavy sections. At much higher levels, the addition of Nickel Can make a class of castings called NiHArd used for high strength, high heat resistance and high resistance to abrasion.

Werkstoffe # 1.2080 is a high carbon chomium tool steel.1.9-2.2% carbon; 11-13%chrome; I have no idea what you might mean by raw malleable parts in this context.

You should now be able to speak somewhat clearly with foundries or castings sales men. The tool steel parts you should talk to machine shops,

NONE of These will be Inexpensive by any stretch of the imagination.
