When measurements are made on a curved surface the radius of curvature must be greater than 0. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. If you feel that your comments have not received a fair hearing you a8000 make your views known to the ASTM Committee on Standards, at the address shown below.

Also, because the magnets or probes aatm the various measuring instruments are small, different degrees of surface roughness or surface curvature will vary the magnetic linkage with the material being measured.

Measurements may be made either before or after performance of the tension aastm. Link to Active This link will always route to the current Active version of the standard. Accordingly, if additional estimates of ferrite content are made by magnetic or metallographic methods, they can be expected to differ from the diagram value.
Similar information is available in Table X1. ASTM Axtm e1. Download Now White Paper: They shall not apply unless specied in the order, in which event the specied methods of ferrite content estimation shall be employed by the manufacturer before shipment of the castings. Methods are described for estimating ferrite content by chemical, magnetic, and metallographic means.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The quantity of asstm in the structure is fundamentally a function of the chemical composition of the alloy and its thermal history.

All measurements shall be made on material after the solution heat treatment required by the applicable product specication, or, if any subsequent solution heat treatment is employed, then after sstm nal solution heat treatment.

If a comparison is made of ferrite content estimated from a product analysis performed by the purchaser, with that estimated from the heat analysis see 7. 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 specied. The gures immediately above and below on the lines U and L indicate the probable upper and lower bounds of the ferrite range that may be expected.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
