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 asgm loaded elements in welded structures, etc.

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.

If flash control is required, please specify at time of quotation or order placement. 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 atsm.

Round and shaped tubing shall meet the required tensile properties such as tensile strength, yield strength, and elongation. When properly exposed to the atmosphere, this steel can be used bare unpainted for many applications. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition Note 2.

A847 Tubing

As a standard under ASTM A, electric resistance welded tubing is normally a874 without removal of inside flash. The atmospheric corrosion resistance of this steel in most envi-ronments is substantially better than carbon steel with or without copper addition Note 2. This abstract is a brief summary of the referenced standard.

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.

Combining values from the two systems may result in non-conformance with the standard. A number in parentheses indicates the year of a8447 reapproval. Historical Version s – view previous versions of standard. Note 2 — For methods of estimating the atmospheric corrosion resistance of low alloy steels, see Guide G or actual data.

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. ATolerances include allowance for convexity or astk. Outside dimension tolerances for square and rectangular tubing shall not exceed the specified plus and minus tolerances.

When this steel is used in atsm construction, the welding procedure shall be suitable for the steel and the intended service. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Within the text, the SI units are shown a47 brackets. It is not required however for squares and rectangles or other shapes under A AApplies to specified wall thicknesses 0. Length tolerance for structural tubing shall be in accordance with the specified values.

Under ASTM A, the corner radius for square and rectangular tubing shall not exceed three times the corner radius.

Commonly referred to as weathering steel, ASTM A Type 4 high strength, low alloy HSLA steel utilizes elements such as copper, chromium, nickel axtm silicon to enhance the protection and resistance to atmospheric corrosion. ABecause of the degree to which phosphorus segregates, roduct analysis for this element a487 not technologically appropriate for rephosphorized steels unless misapplication is clearly indicated.

Twist tolerances for square and rectangular structural tubing shall be indicated. NOTE 2-For ast of estimating the atmospheric corrosion resistance fo low alloy steels see Guide G or actual data.

For lighter wall thicknesses, elongation will be by agreement. NOTE 1-Products manufactured to this specification may not be suitable for those applications where low temperature notch toughness properties may be z847, such as dynamically loaded elements in welded stuctures, etc.

When aetm steel is used in welded construction. Tubing having other dimensions may be furnished provided such tubing complies with all other requirements of this specification. Heat and product analysis shall be performed wherein steel materials shall conform to the required chemical composition for carbon, manganese, phosphorus, sulphur, and copper.
