The steel making process exerts its own form of abuse on equipment.  Heat, thermal cycling,  sharp product edges, abrasion, erosion, and impact all can play a part in the damage and wear of a roll.  Gouges, galling, cracks, cuts, dishing can be the results of every day steel producing. The carbide armor is made to endure and excel where other coatings can't.  By combining the laser clad process with carbide held in an alloy matrix, rolls that utilize MM material will endure a mills most challenging applications.
