tailieunhanh - Standard Specification for High-Strength Low-Alloy Structural Steel, up to 50 ksi [345 MPa] Minimum Yield Point, with Atmospheric Corrosion Resistance

This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition (see Note 1). When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition. This specification is limited to material up to 8 in. [200 mm] inclusive in thickness. | Designation A588 A588M 15 American Association State Highway and Transportation Officials Standard AASHTO No. M 222 Standard Specification for High-Strength Low-Alloy Structural Steel up to 50 ksi 345 MPa Minimum Yield Point with Atmospheric Corrosion Resistance1 This standard is issued under the fixed designation A588 A588M the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.
