Strip tolerance products may be available in widths wider than ? Within the text, the SI units are shown in brackets.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the speci?
However, unless the order speci? The values listed are not exact conversions of the values listed in the inch-pound tables but instead are rounded or rationalized values. NOTE 1—The term weight is used when inch-pound units are the standard. However, under SI the preferred term in mass.

It is normally produced as a fully killed steel. Elements such as aluminum may be added in sufficient amounts to control the austenitic grain size. The elements comprising the desired chemical composition are speci? When the maximum manganese limit exceeds 1. Table 3 shows requirements for additional elements. Limits on such elements are by agreement between purchaser and supplier. Each of the elements listed in Tables 2 and 3 and additional elements agreed upon by the purchaser and the supplier shall be included in the report of heat analysis.
When the amount of copper, nickel, chromium, or molybdenum is less than 0. When the amount of vanadium, columbium, or titanium is less than 0. The strip may be subjected to product analysis by the purchaser either for the purpose of verifying that the chemical composition is within speci? The results of analyses taken from different pieces within a heat may differ from each other and from the cast analysis.
When agreed by purchaser and supplier, other silicon ranges are permissible. Dimensions, Mass, and Permissible Variations 9.

NOTE 2—Camber tolerances as shown in the table are for any 8 ft.
For strip length under 8 ft. NOTE 3—When the camber tolerances shown in Table 8 are not suitable for a particular purpose, cold-rolled strip is sometimes machine straightened.
Over 12 Through 11? 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. NOTE a628 tolerances as shown in the table are for any mm length. For strip length under mm, camber tolerance shall be subject to negotiation.
