ASTM , Ferrite content (CF8M) – Metal and Metallurgy engineering – Eng-Tips

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Students Click Here Join Us! Similar information is available in Table X1. Methods are described for estimating ferrite content by chemical, magnetic, and metallographic means. Estimation of Ferrite Content 7.

The ferrite content may be limited by purchase order requirements or by the design construction codes governing the equipment in which the castings will be used. Because of segregation, the chemical composition, and, therefore, the ferrite content, may differ from point to point on a casting.

The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. ASTM D e1. A number in parentheses indicates the year of last reapproval. Join your peers on the Internet’s largest technical engineering professional community. The quantity of ferrite in the structure is fundamentally a function of the chemical composition of the alloy and its thermal history.

When measurements are made on a curved surface the radius of curvature must be greater than 0. BoxN. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

Measurements may be made either before or after performance of the tension test. 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. The estimates of ferrite content from magnetic measurements S1 or from point counts S2or both, if ordered by the purchaser, also shall be reported. Combining values from the two systems may result in nonconformance with the practice.

Current edition approved Mar.

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.
