Steel type from a sample
Steel type from a sample
(OP)
Hi everybody,
We have an old magnet with a big yoke we would like to reuse for a new test. It is 25 years old. We got some drawings (paper drawings!) but there is not information about the material; what steel it is.
We want to run some simulations and we need to know the properties.
How easy is to get a sample, send it to a lab and find out the type of material? is it expensive?
Another option would be measuring the magnetic properties of the sample.
thank you
regards,

And when?
If it was old, like from before 1985 I would bet that it is Armco A.

It was built in Russia in 1990. It is a big yoke of ca.4 meters in length and height (octagon). The wall thickness is 200-250mm. Like 100 metric tons
The people who make the simulations think it could be iron XC10 (1.0301), it seems very high percentage of iron (because of its magnetic properties)

Is there a location where you could cut or core drill a slug of material and have the magnetic properties measured?
I am sure that you need initial perm, avg perm to some specified field level, and saturation magnetization.
Since the magnetic properties depend on more than just composition why not go directly to what you need?

Taking a sample from such big part would not be a problem, how big should it be?
cheers,

Any chance of a photo?

My concern is how to get the sample part. If we cut in the magnet it will heat up changing the properties.
How can we get the sample without affecting the properties?
thank you

A simple BH test will only require a small sample, say 10mm diameter x 10mm length.
