MATERIAL CHANGED STATE TO PERMANENT MAGNET
MATERIAL CHANGED STATE TO PERMANENT MAGNET
(OP)
Please if someone has experiance with following.
We have bar diameter 80 mm and lenght 1250 mm, material is EN 34CrNiMo6 (AISI 4337/4340).
State of material is quenched and tempered.
But after machining on lathe it is acting as permanent magnet.
Is that normal for this type of material, or is it possible that it was not heat threated?
Best regards

Often after MPI one will degauss the parts to eliminate the residual magnetism.
