Through SI UNITS Note 1—Camber is the greatest deviation of a side edge from a straight line, the measurement asm taken on the concave side with a straight edge.
Ingot cast rimmed, capped and semi-killed steels are subject to limited availability. For strip length under mm, camber tolerance shall be subject to negotiation. Notwithstanding the absence of a signature, the organization submitting the EDI 5 Note 2—Camber tolerances as shown in the table are for any 8 ft. Normal coiling or piling does not necessarily provide a denite positioning of the slitting burr.
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.
Test Reports and Certication Mill inspection by the purchaser shall not interfere unnecessarily with the manufacturer’s operation. B The analysis shall be reported.
ASTM A Carbon Steel, Tempers 4 or 5, Composition Spec
A small amount of cold rolling skin-rolling will prevent this tendency, but the effect is only temporary due to a phenomenon called aging.
Note 3—When the camber tolerances shown in Table 10 are suitable for a particular purpose, cold-rolled strip is sometimes machine straightened. 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.
The use of a lighter load results in a loss of sensitivity, while a heavier load leads to a loss in accuracy. However, such products are technically classied as cold rolled sheet.
There are applications or requirements that necessitate additional controls or limit the choice of processing methods. Combining values from the two systems may result in non-conformance with the standard.
When requested, heat analysis shall be reported to purchaser or his representative. Asstm tolerance for check testing, of two Rockwell points on the B scale below the minimum and above the maximum of the range specied, is commonly allowed to compensate for normal differences in equipment. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements.
Elongation in 2 in. The phenomenon of aging is accompanied by a loss of ductility with an increase in hardness, yield point, and tensile strength. However, under SI the preferred term is mass.

Other tempers vary in a similar way. Over 12 to Over The contents, results, and technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC. NOTE 1—the term weight is axtm when inch-pound units are the standard.
The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. These elements are considered as incidental and are not normally determined or reported. Questions or comments about MatWeb? This nish is especially suitable for lacquer or paint adhesion, and is benecial in aiding drawing operations by reducing the contact friction between a190 die and the strip.

This test requirement is generally the Rockwell hardness test. It is intended for deep drawing applications where such surface disturbances are a10 objectionable.
