Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength
ABSTRACT
This specification covers hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength steel sheet and strip, in coils and cut lengths. The steels covered here are: Commercial Steels of types A, B, C, and D; Drawing Steels of types A and B; Structural Steels of grades 30 [205], 33 [230], 36 [250] (with Types 1 and 2), 40 [275], 45 [310], 50 [340], 55 [380], 60 [410], 70 [480], and 80 [550]; High-strength Low-alloy Steel of classes 1 and 2 in grades 45 [310], 50 [340], 55 [380], 60 [410], 65 [450], and 70 [480]; High-strength Low-alloy steels with improved formability in grades 50 [340], 60 [410], 70 [480], and 80 [550]; and Ultra-high Strength Steels of types 1 and 2 in grades 90 [620] and 100 [690]. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, phosphorus, sulfur, aluminum, silicon, copper, nickel, chromium, molybdenum, vanadium, niobium, titanium, nitrogen, and boron. Except for Commercial and Drawing steels, all other steels shall undergo two tension tests, and shall conform to the following mechanical requirements: yield strength, tensile strength, and elongation. All steels shall undergo bending tests.
SCOPE
1.1 This specification covers hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength 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 SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

3.2.1.1 Discussion—Aging also increases the tendency toward stretcher strains and fluting.
3.2.2 inclusion control, n—the process of reducing the volume fraction of inclusions or modifying the shape of inclusions to
improve formability, weldability, and machinability.
3.2.2.1 Discussion—Inclusions, especially those elongated during the rolling process, create the conditions for initiating or
propagating cracks when the material is stretched or bent during the manufacture of a part (or both). The adverse effects of
inclusions are minimized by reducing the content of inclusions in the steel or by altering the shape of inclusions through the use
