compare steel types
(OP)
Hi everyone,
I am building a magnet that will go into vacuum. It must be small (chamber limitations) and reach 0.1T
As of now I am using steel 1018 but read in a journal that 1010 was used with better results.
I can't seem to find anywhere to compare these too steels (mu and other parameters) as well with other steels.
Question 1: anyone know where I can find such information?
I also found out that supermalloy has a very high mu. that would help me reduce the current I run thus reducing the heat created as a result.
Question 2: does anyone know if supermalloy can go into vacuum and if it can be shaped on a lathe machine?
thanks guys

RE: compare steel types
1010 will have a slightly higher magnetic output than 1018, becuase it has less carbon in it. For most applications, you won't notice a difference. There is data on this in the scientific literature, but probably scattered around a number of different papers.
Supermalloy can go into a vacuum, but it is processed as very thin sheets so you will not be able to shape it on a lathe.
Supermalloy will produce much less magnetic output than 1018 or 1010 steel, unless you are taking about an AC application.
RE: compare steel types
It is for a DC application.
Do you (or anyone else) have a good idea for something else that I can use instead of 1018 with a higher mu?
Thanks

RE: compare steel types
If you can afford it, Vanadium Permendur will have a higher output than iron/steel. It's very expensive and you have to heat treat it to get maximum properties.
RE: compare steel types
I can offer Electrical Core Iron Rod (.02% max Carbon) or Electomagnetic Iron (pure Iron) Strip (.008 max.% Carbon) Either one will offer a very low Hc and high permability.
Let me know if I can help!

RE: compare steel types
but MagneticIronGuy, your ideas might work.
thanks a lot
