NOTE 2-For methods of estimating the atmospheric corrosion resistance fo low alloy steels see Guide G or actual data. Referenced Documents purchase separately The documents listed below are referenced a8847 the subject standard but are not provided as part of the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
Tubeco, Inc. | Specs – ASTM A High Strength Low Alloy Steel Pipe and Tube
When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications. Within the text, the SI units are shown in brackets.
When this steel is used in welded construction, the welding procedure shall be suitable for the steel and the intended service. Outside dimension q847 for square and rectangular tubing shall not exceed the specified plus and minus tolerances. When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications.
Heat and product analysis shall be performed wherein steel materials shall conform to the required chemical composition for carbon, manganese, phosphorus, sulphur, and x847. 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.
For lighter wall thicknesses, elongation will be by agreement. For a complete listing of all tubing sizes produced by Valmont, please astk our Steel Tubing Product Catalog.
The atmospheric corrosion resistance of this steel in most envi-ronments is substantially better than carbon steel with asfm without copper addition Note 2. Note 2 — For methods of estimating the atmospheric corrosion resistance of low alloy steels, see Guide G or actual data. ATolerances include allowance for convexity or concavity.
A number in parentheses indicates the year of last reapproval. BIf chromium and silicon contents are each 0. As a standard under ASTM A, electric resistance welded tubing is normally astj without removal of inside flash.
Chemical composition Grade Mfg. ABecause of the degree to adtm phosphorus segregates, roduct analysis for this element is not technologically appropriate for rephosphorized steels unless misapplication is clearly indicated. Historical Version s – view previous versions of standard. 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.
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. This abstract is a brief summary of the referenced a84.
ASTM A | a steel
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.
Twist tolerances for square and rectangular structural tubing shall be indicated. 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.
For rectangular sections, the tolerance calculated astj 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. Under ASTM A, the corner radius for square and rectangular tubing shall not exceed three times the corner radius. 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.
Round and shaped tubing shall meet the xstm tensile properties such as tensile strength, yield strength, and elongation. Tubing having other dimen-sions may be furnished provided such tubing complies with all other requirements of this specification.
It is informational only and not an official part of the astn the full text of the standard itself must astj referred to for its use and application.
