This specification covers the general requirements for hot-rolled, heavy-thickness, and high-strength low-alloy with improved formability sheet and strip coils. These coils are normally produced from rimmed, capped, or semi-killed steel. Steels may be produced as ingot-cast or strand-cast. Cast or heat analysis shall be made to determine the conformance with the requirements. For steels other than non-killed (capped or rimmed), product analysis may be made. The chemical analysis shall conform to the specified amounts of carbon, manganese, phosphorus, sulfur, silicon, and copper. Steels may or may not be subjected to tension test requirement. Specimen preparation and test methods are discussed. The mechanical property requirements, number of specimens, test locations, and specimen orientation shall be in accordance with the applicable product specification. Tolerances for the dimensions of sheet and strip coils are specified.
