Finish
Surface Finish—Unless otherwise specified, the bars shall have a
commercial bright smooth surface finish consistent with the cold
finishing operations specified in 6.4.
Bars that are thermal treated after cold finishing may have a
discolored or oxidized surface.
Oiling—The bars shall be given a surface coating of oil or other
rust inhibitor to protect against rust during shipment.
Workmanship—The bars shall be free of pipe, cracks, and flakes.
Within the limits of good manufacturing and inspection practices,
the bars shall be free of injurious seams, laps, segregation, or
other imperfections that, due to their nature, degree, or extent,
will interfere with the use of the material in machining or
fabrication of suitable parts.

Special Surface
When inspection standards more restrictive than visual inspection
are required, special surface may be specified.
Restricted Cast or Heat Analysis
When required, the purchaser may specify restrictive cast or heat
analysis limits on one or more elements. The degree of restriction
and the number of elements so restricted are both subject to
agreement between the manufacturer and the purchaser.
Restricted Decarburization
The purchaser may specify a maximum affected depth of
decarburization when required for special applications, subject to
agreement between the manufacturer and the purchaser.
Nonmetallic Inclusion Requirements (Microscopical)
When nonmetallic inclusion requirements are specified, the samples
for testing shall be taken on a longitudinal direction midway
between the center and the surface of the material. The area of the
sample to be examined should be agreed upon between the purchaser
and the manufacturer, and the test specimen should be hardened by
heating and quenched before being polished to avoid pits. The
rating of the inclusion count should also be agreed upon and be
based upon examination at a magnification of 100 diameters.
Resulfurized steels are not subject to inclusion ratings.
Restricted Incidental Elements
The purchaser may specify limiting maximum requirements for copper,
nickel, chromium, or molybdenum subject to agreement between the
manufacturer and the purchaser.
Grain Size
The steel shall conform to either the coarse austenitic grain size
(except as stated in S6.2 in ASTM A311), or the fine austenitic
grain size requirement of Specification A29/A29M.
Certain elements, or combinations of elements, such as manganese,
sulfur, and lead tend to produce grain refinement and it is
technically inappropriate to ensure coarse grain size as measured
by the McQuaid-Ehn test on high manganese, high sulfur, and leaded
steels such as 1144, 1151, and 1141.
