When edge, width and thickness q109 not dened by this table, tolerances are by agreement between producer and supplier. Bend at upon itself in any direction. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This edge is produced when the width tolerance and edge condition are not as exacting as for No.
Cold-rolled carbon strip specified to temper numbers shall conform w109 the Rockwell hardness requirements.
NOTE 2—A typical ordering description is as follows: For strip length under 8 ft. Over 12 to Over Materials and Manufacture 5. W 5 Width of strip, in. An above average surface with better brightness and lower Ra values, sometimes referred to as No.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. When the above aging characteristics are undesirable, special killed generally aluminum killed steel is used.
ASTM A Carbon Steel, Tempers 4 or 5, Composition Spec
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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.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 controlled to prevent oxidizing of the strip surface.
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. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
These elements are considered as incidental and are not normally determined or reported. Over 12 12 Through 12 Specied Width, mm Over C The analysis shall be reported.
Note 3—When the camber tolerances shown in Table 10 are suitable for a particular purpose, cold-rolled strip is sometimes machine straightened.
Product analysis is appropriate on these types of steel only when misapplication is apparent or for copper when copper steel is specied. Specied thickness must be within qstm stated for specied width. Historical Version s – view previous versions of standard. Data sheets for overmetals, plastics, ceramics, and composites.
There is some overlapping among zstm different scales, but the best scale to use in any given case is the one which will give the maximum penetration, without showing undue evidence of impression on the undersurface and without exceeding B or its equivalent on the dial. However, such products w109 technically classified as cold rolled sheet. Originally published as A — 26 T.
Property Data This page displays only the text of a material data sheet.
The exact processing by different manufacturers will naturally vary slightly, so that absolute identity cannot be expected in their commercial tempers of cold-rolled strip. Normal coiling or piling does not necessarily provide a denite positioning of the slitting burr.
A Over 12 34 Specied Thickness, in. When requested, heat analysis shall be reported to purchaser or his representative. Combining values from the two systems may result in non-conformance with the standard.
ASTM A109 Grade 1 hard
Last previous edition A — It is intended for deep drawing applications where such surface disturbances are not objectionable. NOTE 1—the term weight a1009 used when inch-pound units are the standard.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Tolerances for Thickness, in. It is also used to impart surface nish, or affect hardness or other mechanical properties, or to improve atness. We appreciate your input. Rejection and Rehearing However, under SI the preferred term is mass.
This test requirement is generally the Rockwell hardness test. Note 2—Camber tolerances as shown in the table are for any mm length. Number 3 nish is the highest quality nish commonly produced and is particularly suited for bright plating.
It is the general experience that most identied parts can be satisfactorily produced from one of the tempers. Minimum 15T90 30T76 B A small amount of cold rolling skin-rolling will prevent this tendency, but the effect is only temporary due to a phenomenon called aging.
