　　原文名稱：Standard Specification for Steel, Strip, Carbon and High-Strength, Low-Alloy, Hot-Rolled, General Requirements for

　　范 圍：This specification covers the general requirements for hot-rolled steel strip in coils and cut lengths. It applies to carbon steel and high-strength, low-alloy steel furnished as hot-rolled. Hot-rolled material shall be furnished hot-rolled, not annealed, or pickled. The chemical composition shall be in accordance with the applicable product specification. Where the material is used for fabrication by welding, care must be exercised in the selection of chemical composition or mechanical properties to ensure compatibility with the welding process and its effect on altering the properties. A heat analysis shall be conducted to determine the percentage of elements specified or restricted by the applicable specification. The specimens shall be subjected to bend and tension tests.
