Magnetic saturation B-H curve 1

[MrWhite10]

Good evening,
I have been using a software for a FEM simulation, but there is not present the materials which i need in the library of this software. Therefore, I have to add two non linear material in the library, but i need to know the B-H curve (B = magnetic induction, H = magnetic field strength). Where can i find these information for the following materials?
- AISI 430F (ASTM A 838 Alloy 2)
- AISI 420 (ASTM A 176)

Go to Carpenter Technology data sheets, they are about your only hope.

I can do absolutely anything. I'm an expert!

According to the ASM Reference Book

ASTM A838/A838M Alloy 1 Grade 3 has a relative pereability of 600-1100, a coercivity of <557 A/m, and a saturation Ms of 1.0 T, obtail from bar (6.35mm<d<41.28mm) and ring test.

Hardly an electrical steel...wherer losses are an issue.

I presume that these are for cores, hopefully near DC.

You can get generic 430 data in the FEMM material files. Carpenter will supply detailed data but first you must be a customer. I've never encountered data on 420. A good supplier like Carpenter can supply data on any material they produce and may even test material they don't produce if you ask really nicely.

Data for 420 is not readily available, since it was not designed as a magnetic grade, magnetic properties are not in control during manufacturing. Also, the mag properties vary a lot with conditions:
when applied an H field of 250 Oe, the following results could be obtained:
1. cold worked:
Bs = 16,500Gs, Br= 6,000Gs, Hc = 19 Oe
2. cold worked + annealed:
Bs = 18,000Gs, Br= 10,000Gs, Hc = 7 Oe
3. cold worked + hardened + tempered (450C):
Bs = 11,50000 Gs, Br= 7,000Gs, Hc = 65 Oe
