I have a part that I need to make and the design calls for 431 stainless steel because of its magnetic properties. This part will hold another mart that is magnetic. I am having a hard time finding 431 stainless. Would 409 stainless steel work for this?
Are all ferritic stainless steels ( 409...
I was able to get some of this 8020 style extrusion framing for free. But I can't seem to identify the manufacture. It is 90mm x 90mm. It is not 8020.
Does anyone know who makes this?
We are trying to design a low cost expandable flight tube that can cut down the air scatter of x-rays. This flight tube need to expand like a bellows from 100mm collapsed to about 800mm fully extended. It needs to have a inside dimension of 300mm x 300mm square ( it could also be round). I was...

Thanks
Wondering if anyone has prior experience with cooling with copper braids? I have a OFHC copper block that is 100mm x 20mm x 20mm being hit with 30 watts of x-rays. I am cooling this block via indirect cooling with copper braid . There are 4 copper braids that are 1/4" dia and 6 " long. (...
I need to put several small holes in a piece of .300mm thick X 1.5mm dia tungsten. The holes need to be arranged in a succession of sizes from .005mm - .020mm dia. I have tried laser cutting but the edges are very rough and I need these to be a perfect circle. All of my EDM vendors say that they...
