Roll Technology The forged roll characteristics that determine roll performance (microstructure, depth of hardness and residual stress) are achieved by the proper combination of roll chemistry and heat treatment. The full coil static induction hardening method that is unique to Union Electric Steel Corporation optimizes these critical roll attributes. Cryogenic treatment of the "as quenched" roll is utilized for roll applications that require a constant microstructure and hardness profile from new to discard diameter.   Current Roll Grades and Applications (Click here for MSDS for forged rolls)   COLD MILL - WORK and INTERMEDIATE ROLLS HCR 3CR 3CRMO 4CRMO 5CR 5CRDH   HOT MILL - WORK ROLLS 5CRMO 5CR80MO SDS II   COLD MILL - BACK-UP ROLLS UEHM 3CRMO 5CRMO 5CR80MO   HOT MILL - BACK-UP ROLLS UEHM 5CRMO 5CR80MO       Export Product Packaging Information    Links to Printable Product Data Sheets Requires Adobe Acrobat Reader
