ASTM International – Standard References for ASTM A / AM – 14
The quantity of ferrite in the structure is fundamentally a function of the chemical composition of the alloy and its thermal astk. Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration.
Because of segregation, the chemical composition, and, therefore, the ferrite content, may differ from point to point on a casting. Are you an Engineering professional?
It’s easy to join and it’s free. Therefore, the precision of the ferrite content estimated from chemical composition depends on the accuracy of the chemical analysis procedure. Sources of error include the following: It is the responsibility of the user of this standard 8a00 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 qstm. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Regarding 2 and 3you need to know the niobium and nitrogen content of your steel before you carry out the calculation.

These may so alter the magnetic response of the alloy that the indicated ferrite content is quite different from that of the same chemical composition that has undergone different thermal treatment.
