Description:
1) Size: as requested
2) Hardness: as requested
3) Chemical Composition: as requested
These rolls are characterized by spherical graphite. Its mechanical properties are similar to that of alloy indefinite chilled rolls except that its strength is higher than the latter.
Application: Wire rod, structural steel and narrow-band strip mill.
