magnetic properties of DIN EN 10025- S355J0 steel 1

[dsogge]

Anyone have the magnetic permability of DIN EN 10025-S355JO 1.0553 steel.

This is a Maganese steel with 1.6% Mn, .55% Si, .22% C, .55Cu and some other trace elements. It's consider a structural steel.

I think it has the following equivalent numbers;
St52-3u
SS490B
E36-3
50C
Fe510C
Fe510C
AE355C
16Mn
2132-01
2134-01
St510C
NS12153
E355C
Fe570HT

It should look like any generic carbon steel.
Its perm and sat will be highly dependent on the specific thermo-mechanical history. The properties are likely to vary quite a bit from lot to lot.

the permeability is a structure and purity sensitive property, so the structure, e.g. grain size, and purity, especailly O,C,N,S contents, will drastically affect its permability. Also, the permability is magneitc field dependent (initial, max, or permeablity under a specific field can vary a lot). while the saturation induction is structure in-sensitive for non-autenitic steel, you can treat other elements as a dilution of pure iron
