Full title and description

ASTM A595/A595M-22 — Standard Specification for Steel Tubes, Low-Carbon or High-Strength Low-Alloy, Tapered for Structural Use. This specification establishes requirements for seam-welded, round, tapered steel tubes produced in three grades (A, B and C) for structural applications, including chemical and mechanical composition, manufacture, dimensions, testing, and ordering information.

Abstract

This specification covers three grades of seam-welded, round, tapered steel tubes for structural use. Grades A and B are low‑carbon or high‑strength low‑alloy steels; Grade C is weather‑resistant steel. Tubes are made from preformed trapezoidal sheet or plate, seam welded, and roll‑compressed cold on a hardened mandrel to final size and properties. Tensile testing is used to determine yield and ultimate strengths.

Scope

The standard applies to seam‑welded, round, tapered steel tubes for structural use produced in welded sizes with diameters from 2 3/8 in (60 mm) to 30 in (762 mm) and wall thicknesses from 0.1046 in (2.66 mm) to 0.375 in (9.53 mm). It permits modification of the round cross section to other shapes without retesting (by agreement) and defines requirements for material (hot‑rolled, aluminum‑semikilled or fine‑grained killed steel), manufacturing, mechanical properties, chemical composition, testing, and ordering information. Values are stated in SI and inch‑pound units (each system is to be used independently).

Key topics and requirements

• Three grades: Grade A and Grade B (low‑carbon or HSLA), Grade C (weather‑resistant steel).
• Manufacture: trapezoidal sheet/plate preformed, seam welded, then cold roll compression on a hardened mandrel.
• Dimensional range: diameters 2 3/8 in to 30 in (60–762 mm); wall thickness 0.1046–0.375 in (2.66–9.53 mm); tapering by agreement.
• Chemical composition limits and heat analysis requirements for each grade; silicon/aluminum summation requirements for mechanical properties; additional limits for HSLA elements where specified.
• Mechanical property requirements (minimum yield and tensile strengths and elongation) with separate limits for Grades A, B and C.
• Required testing: tensile tests to determine yield and ultimate tensile strength; referenced ASTM test methods for mechanical and chemical analysis.
• Ordering information and supplementary requirements (size, wall thickness, taper, extra test material, and any purchaser‑specified elements).

Technical tables and specific element and mechanical limits are provided in the standard text.

Typical use and users

Used by structural steel fabricators, manufacturers of tapered steel poles and members, civil and structural engineers, specifiers, procurement professionals, and testing laboratories. Typical applications include structural members, tapered columns and poles, trusses, and other load‑bearing tubular components where standardized tapered tube properties and testing are required.
