AApplies to specified wall thicknesses 0. NOTE 1-Products manufactured to this specification may not be suitable for those applications where low temperature notch toughness properties may be important, such as dynamically loaded elements in welded stuctures, etc.
When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Length tolerance for structural tubing shall be in accordance with the specified values.
This standard is issued under the fixed designation A ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. As a standard under ASTM A, electric resistance welded tubing is normally ast without removal of inside flash. For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension.
If flash control is required, please specify at time of quotation or order placement. This specification covers standard requirements for cold-formed welded and seamless high-strength, low-alloy round, square, rectangular, or special shaped structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes where high strength and enhanced atmospheric corrosion resistance are required.

Under ASTM A, the corner radius for square and rectangular tubing shall not exceed a47 times the corner radius. When this steel is used in welded construction, the welding procedure shall be suitable for the steel and the intended service.
When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications. For lighter wall thicknesses, elongation will be by agreement. According to ASTM A, the weld seam location for square, rectangle and other special shaped tubing shall not be located within the corner radius unless specified by the customer or manufacturer.
Please contact one of our knowledgeable sales staff members who will assist you with any further questions regarding this specification or with your specific tubing requirements. It is not required however for squares and rectangles or other shapes under A NOTE 2-For methods of estimating the atmospheric corrosion resistance fo low alloy steels see Guide G or actual data. The atmospheric corrosion resistance of this steel in most q847 is substantially better than carbon steel with or without copper addition Note 2.
The x847 stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
This abstract is a brief summary of the referenced standard. Wstm this steel is used in welded construction.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ABecause of the degree to which phosphorus segregates, roduct analysis for this element is not technologically appropriate for rephosphorized ast unless misapplication is clearly indicated.

ATolerances include allowance for convexity or concavity. Outside dimension tolerances for square and rectangular tubing shall not exceed the specified plus and minus tolerances.
A number in parentheses indicates the year of last reapproval. Within the text, the SI units are shown in brackets. Link to Active This link will always route to the current Active version of the standard. Commonly referred to as weathering steel, ASTM A Type 4 high strength, low alloy HSLA steel utilizes elements such as copper, chromium, nickel and silicon to enhance the protection and resistance to atmospheric corrosion.
Heat and product analysis shall be performed wherein steel materials shall conform to the required chemical composition for carbon, manganese, phosphorus, sulphur, and copper. Combining values from the two systems may result in non-conformance with the standard. Note 1 — Products manufactured to this specification may not be suitable for those applications where low temperature notch toughness properties may be important, such as dynamically loaded elements in welded structures, etc.
The atmospheric corrosion resistance of this steel in most envi-ronments is substantially better than carbon steel with or without copper addition Note 2. For a complete listing of all tubing z847 produced by Valmont, please visit our Steel Tubing Product Catalog.
Round and shaped tubing shall meet the required tensile properties such adtm tensile strength, yield strength, and elongation.
Tubing having other dimensions may be furnished provided such tubing complies with all other requirements of this specification. Twist tolerances for square and rectangular structural tubing shall be indicated.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. With the additional elements such as those noted above, the added xstm of the steel itself allows for a lighter wall thickness of steel to be used than for carbon steel tubing in order to meet structural physical requirements.
Tubing having other dimen-sions may be furnished provided such tubing complies with all other requirements of this specification.
