45Mn17Al3低磁钢45Mn17Al3无磁锰钢#热轧圆钢
45 mn17al3 low magnetic steel is a high alloy single-phase austenitic manganese steel. Has good plasticity, high toughness, work hardening tendency, heat expansion coefficient, low resistivity, thermal conductivity and low magnetism physical properties. The non-magnetic building, non-magnetic machinery, mineral prospecting equipment and military and other fields has been widely used. No magnetic steel has been widely used in many electrical products
