aDAMITE rolls

Adamite or Steel Base is a material with Carbon content and mechanical properties between Steel and Iron.The addition of Cr, Ni, Mo and other elements and a special heat treatment process will develop a high wear and fire cracking resistance together with a constant hardness along the working layer.

Application

Intermediate and finishing stands of section mills.
Intermediate stands of bar mills.
Sleeves for Universal stands of heavy section mills.
Vertical Edgers of hot strip mills.
Work Rolls for roughing stands of heavy plate mills.
