ASTM A Carbon Steel, Tempers 4 or 5, Composition Spec

Questions or comments about MatWeb? However, under SI the preferred term is mass. When the above aging characteristics are undesirable, special killed generally aluminum killed steel is used.

A medium soft cold-rolled strip intended for limited bending, shallow drawing and stamping. However, unless the order species the applicable “M” specication designation SI unitsthe material shall be furnished to inch-pound units. Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units.

Originally published as A — 26 T. Questions or comments about MatWeb? Note 2—Camber tolerances as shown in the table are for any mm length. NOTE 2—A typical ordering description is as follows: SiliconB AluminumC, Copper, when copper steel is specied, min A Incidental Elements – In all carbon steels small quantities of certain residual elements unavoidably retained from raw materials are sometimes found, which are not specied or required, such as copper, nickel, molybdenum, chromium, etc.

Over 12 to Over This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet.

The several determinations of any element shall not vary both above and below the specied range. Tolerances for Thickness, in. In the event that the producer is dissatised with the rejection, he may request a rehearing. B Measured 10 mm or more in from edge; and on narrower than 25 mm, at any place between edges.

Rockwell Hardness Maximum approx. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Or if you don’t have an account with us yet, then click here to register. It is recommended that hardness numbers be specied to the same scale as that to be used during testing. A Over 6 Over 9 Through Through 9 12 0. A moderately stiff cold-rolled strip intended for limited bending.

Subscribe to Premium Services Searches: We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. The amount of reduction is greater than that used in skin-rolling see 3.

The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Tensile properties are based on the standard tension-test specimen for sheet metals, see appropriate gure in Test Methods and Denitions A This test requirement is generally the Rockwell hardness test.

TABLE 11 Flatness Tolerances of Cold-Rolled Carbon Steel Strip It has not been practical to formulate atness tolerances for cold-rolled carbon steel strip to represent the wide range of widths and thicknesses and variety of tempers produced. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. However, the document shall clearly identify the organization submitting the document.

Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. Mill inspection by the purchaser shall not interfere unnecessarily with the manufacturer’s operation. C A soft ductile cold-rolled strip intended for deep drawing where stretcher strains or uting are permissible. For strip length under 8 ft. We also ask that you refer to MatWeb’s terms of use regarding this information.

Bend tests shall be conducted in accordance with requirements specified.

Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units.

Test Reports and Certication Note 2—Camber tolerances as shown in the table are for any 8 ft. A small amount of cold rolling skin-rolling will prevent this tendency, but the effect is only temporary due to a phenomenon called aging.

ASTM A109 Grade 1 hard

Elongation in 2 in. An anneal and skin pass is typically used as the nal step for Temper 4 and 5.

However, such products are technically classified as cold rolled sheet. A tolerance for check testing, of two Rockwell points on the B scale below the minimum and aetm the maximum of the range specied, is commonly allowed to compensate for normal differences in equipment.

For Specied Width, in.
