High wear resistance through the whole depth of the working layer due to the presence of secondary chromium carbides dissolved in a tempered martensitic bainitic matrix.
Forged homogeneous structure, excluding the presence of microporosity and pores.
High level of strength and plastic properties of the body and necks.
Hardened working layer with high and constant hardness.
Uniform wear profile, high resistance to shock loads in emergency situations at the mill.
High operating characteristics, ensured by a balanced roll life and regrinding volume.
