Magnetic Properties of Cast vs Wrought
Magnetic Properties of Cast vs Wrought
(OP)
I am looking for information on the difference that may occur in magnetic properties between a wrought part and cast part. Any information is beneficial.
thanks
thanks

Thanks, forgot to add that in there!

Normally such questions arise for military applications like mine sweepers etc.
In SS too,we have 2 categories broadly,magnetic and non magnetic,a few experts might also argue about paramagnetic.
However, Al is non magnetic. If you can be more clear,you could expect meaningful replies.

There need to be questions asked about field strength, frequency (if AC), and so on. This might be an involved question.

I did find a thread at http://www.finishing.com/112/70.shtml discussing differences in magnetic properties between wrought 316 stainless product and its closest casted counterpart CF-8M based on how the chemistry is "balanced" to lend itself better to the process in question. I wonder if that is something to consider (not knowing anything about 1020 steel) in addition to directionality differences.
Have you contacted any fellow metallurgist at Carpenter Alloy, etc.?

Some differences are shown between cast and wrought iron and ditto for steel on p.367 and p.368, respectively. The physical basis probably has something to do with grain/domain size, orientation and degree of anisotropy.

RE: Magnetic Properties of Cast vs Wrought
For a given size, a wrought part will have a higher coercivity than an as-cast part.
With regards to your question as to which has better magnetic properties, that all depends on what you need it to do. Many applications require high coercivity, just as many applications require low coericivity.
RE: Magnetic Properties of Cast vs Wrought
generally the casting will have lower saturation and higher coercive force, but it will depend on the chemistry.
for most applications, if you have gotten by with generic 1020 the casting will look the same to you.

MagMike: sorry for the double post. new here and it took me a while to find the Magnetics forum and by then people were answering on here and couldn't figure out how to delete the posting. won't happen again.
