Magnetic Stainless Steel 416MX
Magnetic Stainless Steel 416MX
(OP)
I have some drawings out for fabrication, with the material specified as stainless steel 416MX. The fabricator came back to me and asked me if I wanted magnetic or non-magnetic. I told him that as far as I know, all 400 series stainles steels are magnetic, and that if I suspect he used 300 series, I would take a magnet to it.
Does this sound like an intelligent conversation? I have been searching Google on magnetic stainless steels, and it seems to be confirming my opinion. The guy I am talking to is a machinist, not an engineer.
Have I sent the job to the wrong place?

RE: Magnetic Stainless Steel 416MX
This material will always be magnetic (at room temp.)
I hope that this is a machined part with no brazing, welding or particular surface finish requirements. 416 is a free machining grade and the high S levels raise hell. But it does cut nice.

RE: Magnetic Stainless Steel 416MX
Kindly inform the machinist that this material is similar to working with AISI Type 410 SS, and see what his response is regarding machining/handling. If you feel comfortable with their response, ask for paperwork to assure that the shop has ordered the correct grade of AISI 416 SS.
RE: Magnetic Stainless Steel 416MX
Thank you.
The part is to be machined and passivated. I was not planning on heat treat. My Atlas Alloys catalogue lists a yield strength of 110ksi, without specifying the heat treat. It sounds like I need to check up on MATWEB.
I tend just to write STAINLESS STEEEL on drawings, but this time I wanted the strength and I did not absolutely care about corrosion resistance.

RE: Magnetic Stainless Steel 416MX
Just asking for 416 will prob. get you normalized or annealed bar at about 40ksi yield and 75ksi tensile. But watch out the minimums are 30/60.
