45Mn17Al3 low magnetic steel is a high alloy single phase austenitic manganese steel. It has good plasticity, high toughness, large work-hardening tendency, large thermal expansion coefficient, high resistivity, low thermal conductivity and low magnetic properties. It is widely used in non-magnetic buildings, non-magnetic machinery, mineral processing and prospecting equipment, military and other fields.

Non-magnetic steel 917, grade 45Mn17Al3, is also classified into - 1 and - 2 grades. The carbon content of 917-2 is slightly higher than that of 917-1 low magnetic steel, and the yield is also higher. The parts used are specific to the geomagnetic forgings of the ship shaft with a diameter greater than 100.
As an economical low magnetic structural steel, 45Mn17Al3 is mainly used to prevent low magnetic components and projects that produce various electromagnetic interference, such as shipbuilding industry and low magnetic construction engineering.
