ASTM A Steel, Strip, High Carbon, Cold Rolled, General Requirements
A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. Strip tolerance products may be available in widths wider than ? Within the text, the SI units are shown in brackets.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
ASTM A682 Grade 1074
Combining values from the two systems will result in nonconformance with the speci? However, unless the order speci? The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values.
NOTE 1—The term weight is used when inch-pound units are the standard.
However, under SI the preferred term in mass. Current edition approved March 10, Originally published as A — Last previous edition A — General Requirements for Delivery 4. Materials and Manufacture 5. It is normally produced as a fully killed steel. Elements such as aluminum may be added in sufficient amounts to control wstm austenitic grain size. The elements comprising the desired chemical composition are speci?
Sstm the maximum manganese limit exceeds 1. Table 3 shows requirements for additional elements. Limits on such elements are by agreement between purchaser and supplier. Each of the elements listed in Tables 2 and 3 and additional elements agreed upon by the awtm and the supplier shall be included in the report of heat analysis.
When the amount of copper, nickel, chromium, or molybdenum is less than 0.
When the amount of vanadium, columbium, asm titanium is less than 0. The strip may be subjected to product analysis by the purchaser either for the purpose of verifying that the chemical composition is within speci? The results of analyses taken from different pieces within a heat may differ from each other and from the cast analysis. When agreed by purchaser and supplier, other silicon ranges are permissible.

ast C Number 3 edge strip with thickness tolerance guaranteed s682 less than 3? This edge is produced when the width tolerance and edge condition are not as exacting as for No. Number of Tests and Retests C When edge, width and thickness are not de? Two additional samples are secured from each end of the coil from which the original sample was taken.
A portion of the coil may be discarded prior to cutting the samples for retest. If any of the retests fail to comply with the requirements, the coil shall be rejected. Rework and Retreatment Unless otherwise agreed to, all tests and inspections, except product analysis, shall be made at the place of production.

When required, minimum coil weights are subject to negotiation. Rejection and Rehearing The material must be adequately protected and correctly identi? In case of dissatisfaction with the results of the test, the manufacturer may make claims for a rehearing.
However, the document shall clearly identify the organization submitting the document. Notwithstanding the absence of a signature, the organization submitting the document is responsible for the content of the document. NOTE 2—Camber tolerances as shown in the table are for any 8 ft. For strip length under 8 ft.
NOTE 3—When the camber tolerances shown in Table 8 are not suitable for a particular purpose, cold-rolled strip is sometimes machine straightened. Over 12 Through 11? 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—Camber tolerances as shown in the table are for any mm length. For strip length under mm, camber tolerance shall be subject to negotiation. Revision to Table 2.
