ASTM A1011/A1011M-00

Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy and High-Strength Low-Alloy with Improved Formability

SCOPE
1.1 This specification covers hot-rolled structural, high strength-low alloy, and high-strength low-alloy with improved formability steel sheet and strip, in coils and cut lengths.
1.2 Hot rolled steel sheet and strip is available in the designations as listed in 4.1.
1.3 This specification is not applicable to the steel covered by Specification A635/A635M.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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.
