Sgac & Sgac - Gr Rolls : : : : Nodular acicular rolls are widely used for hot rolling applications in different type of intermediate, prefinishing and finishing group stands. The material consists of nodular graphite and carbides in martensitic and bainitic matrix. SGAC rolls are more wear resistant than nodular pearlitic rolls. Depending on the primary requirements there are variety of standard and also more alloyed grades used considering rolling mill operational conditions and specially wear resistance which is increasing with hardness drop if compared with standard grades considering the type of groove / caliber.
