ASTM A1011/A1011M-15 pdf free.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.
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.
4. Classification
4.1 Hot-rolled steel sheet and steel strip is available in the following designations:
4. 1. 1 Commercial Steel (CS Types A, B, C, and D, as specified in Table 1).
4. 1.2 Commercial Steel (CS Types A and B combined with chemistry grade per Specification A568/A568M Table X2.3) 4.1.3 Drawing Steel (DS Types A and B, as specified in Table 1).
4.1 4 Drawing Steel (DS Types A and B combined with chemistry grade in accordance with Specification A568/ A568M Table X2.3.
4.1.5 Commercial Steel Chemistry grade in accordance with Specification A568/A568M Table X2. l, with no type specified (CS-1005, CS-1008, CS-1020, and so forth).
4.1.6 Special Forming Steel(SFS)， chemistry as specified in
Table I with carbon manganese limits in accordance with Specification A568/A568M Tables X2. I or X2.2(examplesSFS-1010,SFS-1020,SFS-C0.12-0.18%&mn0.500.80%).
6. General Requirements for Delivery
6.1 Material furnished under this specification shall con- form to the applicable requirements of the current edition of Specification A568/A568M for sheets and Specification A749/ A749M for strip, unless otherwise provided for herein.
7. Chemical Composition
7. I The heat analysis of the steel shall conform to the chemical composition requirements of the appropriate desig nation shown in Table I for CS. DS and SFS. and Table 2 for SS. HSLAS, HSLAS-E and UHSS
7. 1.1 A report of heat analysis will be supplied, if requested, for CS and DS. For materials with required mechanical properties, SS, HSLAS, HSLAS-F, and UHSS, a report of heat analysis is required.
8. Mechanical Properties
8. 1 CS and DS
8.1.1 Typical, nonmandatory mechanical properties for CS and DS for all grades specified in Table I and Specification A568/A568M Table X2. 3 are found in Table 3.
8.1.2 The material represented by all grades specified in Table I and Specification A568/A568M Table X2.3 shall be capable of being bent at room temperature in any direction through 180 flat on itself without cracking on the outside of the bent portion (see the section on bend test in Test Methods and Definitions A370)。 The bend test is not a requirement of delivery. However, if testing is performed by the purchaser, material not conforming to the requirement shall be subject to rejection.
8.2 SS. HSLAS HSLAS-F and UHSS
8.2.1 The available grades and corresponding mechanical properties for SS. HSLAS, HSLAS-F, and UHSS are shown in Table 4.
8.2.1.1 For SS, HSLAS, HSLAS-F, and UHSS, a report is required of mechanical properties as determined by the tension test.
