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.
