A number in parentheses indicates the year of last reapproval. 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. Note 2 — For methods of estimating the atmospheric corrosion resistance of low alloy steels, see Guide G or actual data.

Asgm chromium and silicon contents are each 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 structures, etc.

Round and shaped tubing shall meet the required tensile properties such as tensile strength, yield strength, and elongation. When this steel is used in welded construction.

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

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.

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. If flash control is required, please specify at time of quotation or order placement. Link to Active This link will always route to the current Active version of the 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. Twist tolerances for square and rectangular structural tubing shall be indicated.

For lighter wall thicknesses, elongation will be by agreement. Length tolerance for structural tubing shall be in accordance with the specified values.

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.

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

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

This standard is xstm 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 qstm. AApplies to specified wall thicknesses 0. When properly exposed to the atmosphere, this steel asstm be used bare unpainted for many applications. S847 having other dimensions may be furnished provided such tubing complies with all other requirements of this specification.

For rectangular sections, the tolerance calculated for the larger flat dimension shall also apply to the smaller flat dimension. When this steel is used in welded 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.

Tubing having other dimen-sions may be furnished provided such tubing complies with all other requirements of this specification. Historical Version s – view previous versions of standard.

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