Report on the Effect of Cold Working on the Magnetic Properties of Some Austenitic Manganese Steels
Abstract
Non-magnetic armor plate is usually made from austenitic steels which when cold worked, tend to become magnetic. Samples from a number of widely different types of austenitic alloys suitable for non-magnetic armor were subjected to varying degrees of cold reduction, and studied magnetically. It was found that the high carbon manganese alloys have a great capacity of acquiring high surface hardness upon deformation and of still retaining their weak magnetic characteristics; the low carbon alloys on the other hand, are weakly magnetic for small amounts of cold working but become increasingly magnetic with further reactions. In any case these alloys are all much less magnetic than armor of the "STS" type.
