The quantity of ferrite in the structure is fundamentally a function of the chemical composition of the alloy and its thermal history. Are you an Engineering professional?

Also, because the magnets or probes of the various measuring instruments are small, different degrees of surface roughness or surface curvature will vary the magnetic linkage with the material being measured. Regarding 2 and 3you need to know the niobium and nitrogen aastm of your steel before you carry out the calculation. Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
Methods are described for estimating ferrite content by chemical, magnetic, and metallographic means. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
These may so alter asttm magnetic response of the alloy that the indicated asym content is quite different from that of the same chemical composition that has undergone different thermal treatment.

Because of segregation, the chemical composition, and, therefore, the ferrite content, may differ from point to point on a casting. Sources of error include the following: Register now while it’s still free!

The ferrite content may be limited by purchase order requirements or by the design construction codes governing the equipment in asttm the castings will be used. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Determination of the ferrite content by any of the procedures described in the following practice is subject to varying degrees of imprecision which must be recognized in setting realistic limits on the range of ferrite content specified. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
