It is recommended that hardness numbers be specied to the same astmm as that to be used during testing. Mill inspection by the purchaser shall not interfere unnecessarily with the manufacturer’s operation.
Property Data This page displays only the text of a material data sheet. 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. It is intended for deep drawing applications where such surface disturbances are not objectionable.
Thickness Tolerances Plus or Minus, in. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Temper and Bend Test Requirement 7. Data sheets for overmetals, plastics, ceramics, and composites. This table is presented as a matter of general information. Notwithstanding the absence of a signature, the organization submitting the document is responsible for the content of the document.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Tolerances for Thickness, in.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. An anneal and skin pass is typically used as the nal step for Temper 4 and 5.
Current edition approved Sept.
Minimum 15T90 30T76 B Specied thickness must be within ranges stated for specied width. This specification satm cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet.
ASTM A109 Grade 1 hard
It is common practice to make the Rockwell hardness a190 at a point midway between the side edges on a single thickness only. Within the text, the SI units are shown in brackets. The production of this nish requires extreme care in processing and asrm inspection. This edge is produced when the width tolerance and edge condition are not as exacting as for No.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The amount of reduction is greater than that used in skin-rolling see 3.
We appreciate your input.
C 5 Camber, in. However, some applications are specied as silicon killed. B Measured 10 mm or more in from edge; and on narrower than 25 mm, at any place between edges. 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.
ASTM A Carbon Steel, Tempers 4 or 5, Composition Spec
It is the general experience that most identied parts can be satisfactorily produced from adtm of the tempers. These elements are considered as incidental and are not normally reported.
It is also used to impart surface nish, or affect hardness or other xstm properties, or to improve atness. 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.

See applicable gure in Test Methods and Denitions A A moderately stiff cold-rolled strip intended for limited bending. Proper identication of parts may include visual examination, prints or descriptions, or a combination of these. Number 3 nish is the highest quality asstm commonly produced and is particularly suited for bright plating.
