Alloy 4750/ High Perm 49® is a 48% nickeliron alloy which combines a high saturation flux density (approx. 16000 gauss / tesla) with high magnetic permeability and low core loss. This alloy has the high saturation flux density of any of the nickeliron alloys, making it a versatile alloy.
Feb 24, 2017· The material of Sendzimir work roll is tool steel, die steel and highspeed steel. These are materials of high hardness. The rolls are manufactured under quenching and tempering processes of high temperature. During the tempering process, secondary hardening is used to reach hardness of 6063HRC, 6164 HRC, 6366HRC etc, for different work rolls.
