Title
Standard Practice for Macroetch Testing of Consumable Electrode Remelted Steel Bars and Billets
ASTM International
Publication Date:
May 1, 2007
Scope:
This practice2 covers testing and inspection and is
applicable to bars, billets, and blooms of carbon, alloy, and
stainless steel which have been consumable electrode remelted.
For the purpose of this practice, the consumable electrode
remelting process is defined as a steel refining method wherein
single or multiple electrodes are remelted into a crucible
producing an ingot which is superior to the original electrode by
virtue of improved cleanliness or lower gas content or reduced
chemical or nonmetallic segregation. See Appendix X1 and Appendix
X2 for descriptions of applicable remelting processes.
This practice and the accompanying comparison
macrographs3 are generally applicable to steel bar and
billet sizes up to 225 in.2 [1450 cm2] in
transverse cross section.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. 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.
*A Summary of Changes section appears at the end of this
standard.

of the AISI Committee on General Metallurgy in preparing the
appendix, assembling the macroetch photographs, and assisting with
the text of this practice.
