Highly wear-resistant roll steel for cold rolling mills

摘要

A steel from which rolls for a cold rolling mill are made and which gives to the rolls very excellent wear resistance in addition to thermal shock and spalling resistances and various mechanical characteristics is provided. Said steel comprises:C : 0.70 to 1.50 wt%Si: 0.15 to 1.00 wt%Mn: 0.15 to 1.50 wt%Cr: 2.50 to 10.00 wt%Mo: 1.00 wt% or lessV : 1.00 wt% or lessNi: 1.00 wt% or lessTi: 0.04 to 0.30 wt%with the balance being Fe and inevitable impurities.
