Through 50 Standard Camber Tolerance, mm 10 5 The exact processing by different manufacturers will naturally vary slightly, so that absolute identity cannot be expected in their commercial tempers of cold-rolled strip. Over 12 12 Through 12 Specied Width, mm Over A small amount of cold rolling skin-rolling will prevent this tendency, but the effect is only temporary due to asstm phenomenon called aging.
Tensile properties are based on the standard tension-test specimen for sheet metals, see appropriate gure in Test Methods and Denitions A Notwithstanding the absence of a signature, the organization submitting the document is responsible for the content of the document.

Conformance to SI tolerances is mandatory atm the “M” specication is used. B The analysis shall be reported. Specied thickness must be within ranges stated for specied width.

This analysis shall conform to the requirements shown in Table 1. This test requirement is generally the Rockwell hardness test. It is recommended that hardness numbers be specied to the same scale as that to be used during testing.
However, such products are technically classified as cold rolled sheet. Mill inspection by the purchaser shall not interfere unnecessarily with the manufacturer’s operation. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

There are applications or requirements that necessitate additional controls or limit the choice of processing methods. A medium soft cold-rolled strip intended for limited bending, shallow drawing and stamping. These elements are considered as incidental and are not normally reported. It is the general experience that most identied parts can be satisfactorily produced from one of the tempers.

The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Note 2—Camber tolerances as shown in the table are for any mm length. When the above aging characteristics are undesirable, special killed generally aluminum killed steel is used.

Through SI UNITS Note 1—Camber is the greatest deviation of a side edge from a straight line, the measurement being taken on the concave side with a straight edge. NOTE 2—A typical ordering description is as follows: A Asfm 12 34 Specied Thickness, in.
Originally published as A — 26 T. For strip length under mm, camber tolerance shall be subject to negotiation.
