ASTM A800
ASTM A800
(OP)
Appendix section X1.5 of this spec gives a formula for calculating the composition ration CR from the ferrite content F
CR = 0.9 + (3.38883x10^-2 F)-(5.58175x10^-4 F^2)+(4.22861x10^-6 F^3)
Has anybody got a version where F is the unknown?
Thanks

RE: ASTM A800
Why do you need to re-arrange the central line equation to solve for F in terms of CR?
RE: ASTM A800
I have to do a lot of these.
