SAE 1006 v/s SAE 1008
SAE 1006 v/s SAE 1008
(OP)
Hello
Recently we have changed the supplier for the rotor claw poles of an automotive generator.
earlier MAT was equivalent of SAE 1006.
new MAT is equivalent of SAE 1008.
Current output is low with the new MAT.
Kept constant: All Design parameters
Changes: A slight process change by the new supplier
MAT change
Can anyone suggest why?
Thanks

You need to test magnetic properties to figure it out.

1. Saturation point
2. B-H product
3. Permeability
Apart from these, what else must I look at?

You may need to look at perm at a specific applied field strength.

Thanks for the inputs.
In fact we will be plotting a B-H curve soon. However, are there any specific 'boundary conditions' to be defined for conducting the measurement?
Last time I interacted with a guy who does B-H curve plotting he bombarded me with questions pertaining to these 'boundary conditions'.....of which I have little knowledge.
Any suggestions?

We drop forge the claw poles.
Annealing is done for the SAE1006 parts but not for SAE1008.

Well you should not have far to look to find the problem.

RE: SAE 1006 v/s SAE 1008
Yup, I agree that annealing gives the desired results. However, it costs.
While using the SAE1006, I am additionally trying to cut this additional annealing cost.
Any suggestions (like partial magnetization during processing, etc)??

A good anneal is the only way to improve the magnetic characteristics.

I will look in this direction and let you all know what the results are in a few weeks time.
CHEERS!
