(Specification)Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, with Improved Atmospheric Corrosion Resistance
Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, with Improved Atmospheric Corrosion Resistance
ABSTRACT
This specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance. The material shall follow specified carbon, manganese, and sulfur contents. Tension test shall be performed and material shall comply with tensile strength, yield strength, and elongation requirements. Edges and surface finish of the materials shall conform to specifications. Guidelines for retests are also given.
SCOPE
1.1 This specification covers high-strength, low-alloy, hot- and cold-rolled sheet and strip in cut lengths or coils, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in three types: Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contains additional alloying elements and provides a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in the bare (unpainted) condition for many applications.
Note 1: For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G101.
1.2 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.
1.3 Welding—In general, the steels listed in this specification are weldable with commonly obtained welding electrodes. When the steel is to be welded, a suitable welding procedure based on its composition should be used, taking into account intended use and service temperatures.
Note 2: For a general discussion of the weldability of steel and carbon equivalents, consult Appendix X3 of A6/A6M.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
