Norma ASTM A595 para tubos de aço cônicos para uso estrutural

ASTM A595 Standard Specification for Steel Tubes, Low-Carbon or High-Strength Low-Alloy, Tapered for Structural Use covers three grades of seam-soldada, round, tapered steel tubes for structural use. Grades A and B are of low-aço carbono or high-strength low-alloy steel composition and Grade C is of weather-resistance steel composition. The tube steel shall be hot-rolled alumínio-semikilled or fine-grained killed sheet or plate manufactured by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace. The tubes shall be made from trapezoidal sheet or plate that is preformed and then seam welded. They shall be brought to final size and propriedades by roll compressing cold on a hardened mandrel. A tensile test shall be done to determine the resistência ao escoamento and the ultimate resistência à tração of the tubes.

1.1 This specification covers three grades of seam-welded, round, tapered steel tubes for structural use. Grades A and B are of low-carbon steel or high-strength low-alloy steel composition and Grade C is of weather-resistant steel composition.

1.2 This tubing is produced in welded sizes in a range of diameters from 2 3/8 to 30 in. [60 to 762 mm] inclusive. Wall thicknesses range from 0.1046 to 0.375 in. [2.66 to 9.53 mm]. Tapers are subject to agreement with the manufacturer.

1.3 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 indepedently of the other. Combining values from the two systems may result in non-conformance with the padrão.
