Non-Magnetic Structural Steels

Non-Magnetic Structural Steels

Non-Magnetic Structural Steels

(OP)
Anyone have a good list of magnetic properties for "non-magnetic" steels?

I have an application for designing a vertical reciprocating conveyor(VRC or material handling lift) typically fabricated from A36 structural shapes (W, L, C, HSS sections).  We need to install a lift in a research facility room with MRI (high magnetic field) equipment.  They ask that all parts be of non-magnetic steel.  I also have to address mechanical interlocks & hardware.

I'm thinking of aluminum, 304 stainless.  We have fabricated a 304 stainless lift but I'm not sure of the degree of non-magnatism.

Any references or list would be appreciated.

RE: Non-Magnetic Structural Steels

  When I worked for the Navy, we used non-mag steels on minesweepers.  I remember testing bolts, etc. with a small device (magnometer?).  If you have access to Mil-Spec's, I know their is one on non-mag steels.  It had all of the general properties, including magnetism.  IIRC, it was unclassified so you should be able to get a copy.
  We used a lot of stainless steels (don't remember which type) and monel.  Almost everything was commercially available which surprised me. That was the reason we were using the magnometer, to make sure they met standard without a huge special order.

I designed an MRI building in Cleveland that was totally non-magnetic using timber with stainless steel connections.
