This edge is produced when the width tolerance and edge condition are not as exacting as for No. Workmanship, Finish, and Appearance Login to see your most recently viewed materials here.
The term weight is used asfm inch-pound units are the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The use of a lighter load results in a loss of sensitivity, while a heavier load leads to a loss in accuracy. Within the text, the SI units are shown in brackets. Conformance to SI tolerances is mandatory when the “M” specication is used.
However, under SI the preferred term is mass. The values listed are not exact conversions of wstm values listed in the inch-pound tables, but instead are rounded or rationalized values. B Measured 10 mm or more in from edge; and on narrower than 25 mm, at any place between edges.
When required, minimum coil weights are subject to negotiation. It is intended for deep drawing applications where such surface disturbances are not objectionable.

An anneal and skin pass is typically used as the nal step for Temper 4 and 5. Note 2—Camber tolerances as shown in the table are for any mm length.
Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. For Specied Width, in. 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.

A Over 6 Over 9 Through Through 9 12 0. The strip is 1. No vendors are asgm for this material. Combining values from the two systems may result in non-conformance with the standard.
ASTM A109 Grade 1 hard
Elongation in 2 in. Bend at upon itself in any direction.
This nish is especially suitable for lacquer or paint adhesion, and is benecial in aiding drawing operations by reducing the contact friction between the die and the strip.
A satm ductile cold-rolled strip intended for deep drawing where no surface strain or uting is permissible.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. W 5 Width of wstm, in. Packaging and Package Marking Note 2—Camber tolerances as shown in the table are for any 8 ft.
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 amount of reduction is greater than that used in skin-rolling see 3. It is informational only a019 not an official part of the standard; the full zstm of the standard itself must be referred to for its use and application. C Also for extrusions. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
In bright normalizing the furnace atmosphere is asym to prevent oxidizing of the strip surface. Ingot cast rimmed, capped and semi-killed steels are subject to limited availability. It serves to reduce the tendency of the steel to ute or stretcher strain during fabrication. The tempers are obtained by the selection and control of chemical composition, by amounts of cold reduction, by thermal treatment, and by skin-rolling.
Historical Version s – view previous versions of standard. Product analysis is appropriate on these types of steel only when misapplication is apparent or for copper when copper steel is specied.
NOTE 1—the term weight is used when inch-pound units are the standard. This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel ast. Cold Rolled Strip Vendors: For those uses in which stretcher straining, uting, or breakage due to aging of the steel is likely to occur, the steel should be fabricated as promptly as possible after skin-rolling.
