Magnetic Properties of ASTM A108
Magnetic Properties of ASTM A108
(OP)
We are trying to perform magnetic particle inspection of A108 material. After we send current through the parts, we are finding that there is no residual magnetism. The material does have some chrome and nickel (0.13 and 0.06) and copper (0.16) but shouldn't influence the magnetic properties should it?

Just because a material is ferromagnetic does not mean that it will retain magnetism. This material may be clean enough and annealed well enough so that it has near zero coercivity, and will not stay magnetized when the field is removed.
