HI ALLOYED STEEL Rolls

Alloyed rolls are special steels alloyed with nickel, chromium & molybdenum which is used in breakdown, roughing & intermediate mills for finishing of heavy sections.
These rolls are statically casted and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation.
The rolls are available in a wide variety of composition & properties to suit specific application.
The matrix structure is pearlitic or bainitic depending on the alloy content.
Changing the carbide distribution obtained through controlled chemical composition varies the hardness.
It’s used in finishing rolls for sheet, plate and strip mills.Intermediate and finishing rolls for small section, bar and wire rod mills. Also used as cold mill rolls for ferrous and non-ferrous sheets.
