When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications.

A847 Tubing

AApplies to specified wall thicknesses 0. It is not required however for squares and rectangles or other shapes under A 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.

When this steel is used in welded construction.

ASTM A | a steel

With the additional elements such as those noted above, the added strength 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. 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.

Historical Version s – view previous versions of standard. Length tolerance for structural tubing shall be in accordance with the specified values. This abstract is a brief summary of the referenced standard. Within the text, the SI units are shown in brackets. Under ASTM A, the corner radius for square and rectangular tubing aastm not exceed three times the corner radius.

BIf chromium and silicon contents are each 0. Outside dimension tolerances a8447 square and rectangular tubing shall not exceed the specified plus and minus tolerances. 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.

The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition Note 2. 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.

The atmospheric corrosion resistance aa847 this steel in most envi-ronments is substantially better than carbon steel with or without copper addition Note 2. ABecause of the degree to which phosphorus segregates, roduct analysis for this element is not technologically appropriate for rephosphorized steels unless misapplication is clearly indicated. For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension.

Chemical composition Grade Mfg. Tubing having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.

Combining values from the two systems may result in non-conformance with the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Heat and product analysis shall be performed wherein steel materials shall conform to the required chemical composition for 8a47, manganese, phosphorus, sulphur, and copper. 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.

Twist tolerances for square and rectangular structural tubing shall be indicated. This specification covers standard atm 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.

If flash control is required, please specify at time of quotation or order placement. Tubing having other dimen-sions may be furnished provided such tubing complies with all other requirements of this specification. When this steel is used in welded construction, the welding procedure shall be suitable for the steel and the intended service. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

A number in parentheses indicates the year of last reapproval. For a complete listing of all tubing sizes produced by Valmont, please visit asttm Steel Tubing Product Catalog. When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications.

Commonly referred to as weathering steel, ASTM A Type 4 high strength, low a874 HSLA steel utilizes elements such as copper, chromium, nickel and silicon to enhance the protection and resistance to atmospheric corrosion.

Round and shaped tubing aa847 meet the required tensile properties such as tensile strength, yield strength, and elongation. 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. ATolerances include allowance for convexity or concavity.
