ASTM A1110/A1110M-21

Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes with 52 KSI [360 MPa] Minimum Yield Strength and Impact Requirements

ABSTRACT
This specification covers the manufacturing and testing requirements for cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing used in welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes where impact properties are required. The steel shall be made by one or more of the following processes: basic-oxygen or electric-furnace. The tubing shall be produced in both welded and seamless sizes with a periphery of 88 in. [2235 mm] or less, and a specified wall thickness from 0.148 in. [4 mm] up to 0.875 in. [22 mm]. The welded and seamless tubing can be supplied in two different grades each with a specified impact test temperature.
This specification also covers ordering information, chemical requirements, tensile and charpy requirements, permissible variations in outside flat dimensions for square and rectangular structural tubing, length tolerances for specific lengths of structural tubing, permissible variations in twist for square and rectangular structural tubing, flattening and flaring tests, special shape structural tubing, number of tests, retests, inspection, certification, product marking, government procurement, and packing, marking, and loading.
SCOPE
1.1 This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes where impact properties are required.  
1.2 This tubing is produced in both welded and seamless sizes with a periphery of 88 in. [2235 mm] or less, and a specified wall thickness from 0.148 in. [4 mm] up to 0.875 in. [22 mm].  
1.3 The welded and seamless tubing can be supplied in two different grades each with a specified impact test temperature. Different strength levels, CVN acceptance criteria, and impact test temperatures than listed may be available. To determine their availability, the purchaser should contact the producer (see 4.1.4 and 4.1.13).  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.  
1.5 The text of this specification contains notes and footnotes that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
