Magnetic saturation B-H curve
Magnetic saturation B-H curve
(OP)
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)

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.

RE: Magnetic saturation B-H curve
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
