(OP)
Is their such a thing to Calucalate the amount of Ferrite in a material?
My Specification calls for 15-45% Ferrite.
We are getting differant answers from the european community and the USA community.
Is their differant calculations/formulas?
Composition:
C 0.08
SI 1.50
Mn 1.50
P 0.04
S 0.04
Cr 18-22.0
Ni 9 - 13.0
Mo 3 - 4.0
Mecahnical
YS min 359MPa
TS min 650 MPA
Elongation Min 33%
Ferrite content 15-45%
Can this be done?

Simple calculation method presented by Avesta Sheffield. The formula for Avesta Ferrite Number FNA assumes parallel lines of constant ferrite numbers.
Creq = Cr + 1.5 Si + Mo + 2 Ti + 0.5 Nb
Nieq = Ni + 30 (C + N) + 0.5 Mn + 0.5 Cu + 0.5 Co
FNA = 3.34 Creq - 2.46 Nieq - 28.6
