Magnetic Properties of various SS and tool steels
Magnetic Properties of various SS and tool steels
(OP)
I'm looking to replace a BO1 tool steel with a similar material. The current part has shown signs of corrosion, so the new material needs better corrosion resistance. Importantly, the magnetic permeability of the steel needs to be similar to the BO1 steel.
Does anybody know where I can find the magnetic permeability values for tool steels (especially that of the BO1 steel so that I know what I'm comparing to)?
Thanks in advance

RE: Magnetic Properties of various SS and tool steels
If the chemistry, processing and heat treatments are maintained & similar then the permeability will be similar. Do you know what heat treatment condition is called out on your existing part?
Also, what is the permeability of your current part?

You will need to have some of your current parts tested.
And then decide what properties you need, hardness, toughness, perm, ......
The size and shape of the part matter also as to which alloy you can use.
Could you do with 440C? Or maybe a high strength PH grade (Custom 455 or 465)?
