| Rol-Man® is a high manganese, fully austenitic, quench annealed, non-magnetic, work hardening steel with an exceptionally high level of wear resistance when subjected to work-hardening by shock or high impact pressure while in service. The main characteristic of Rol-Man is superior wear resistance. Severe wear on the surface has a work-hardening effect on the austenitic structure of this steel. This leads to an increase in hardness from 200 BHN (in as delivered plates) up to an in-service hardness of at least 600 BHN. This work-hardening capability renews itself throughout its in-service life. The underlayers which are not work-hardened maintain an excellent resistance to shock and a very high ductility.Information provided by Astralloy, a Nucor Company. |
