Peer reviewed only Published between: Master of Applied Science. Use of A steels containing Awtm Eng-Tips staff will check this out and take appropriate action.
Combining values from the two systems may result in non-conformance with the standard. The greater corrosion resistance of A steel with a more positive corrosion potential does, however, impose a risk of galvanic corrosion with the connection bolts in direct electrical contact.

The mechanical properties of these steels are customarily, but not necessarily, developed by a suitable heat treatment generally referred to as tempering.

In the edition of the Canadian Highway Bridge Design Code, the slip coefficient for clean mill scale and hot dip galvanized surface condition for the W structural steel is specified as 0.
Historical Version s – view previous versions of standard. For example, weathering steel has been used as bridge construction material by the Ministry of Transportation of Ontario MTO Canada sinceand it has been used exclusively since then for structural steel components in highway bridges in Ontario 4. Abstract The primary aim of this experimental research was to provide information on the slip coefficient performance of ASTM A stainless steel material and to ascertain if its behaviour is comparable to that of W Structural Steel.
This protective patina can reduce corrosion rate to less than 0. Proceedings of an International Conference Submersible Technology: Yield Strength, min, ksi [MPa]. Advanced search Show search help. Publishers Content Coverage Privacy.
Although test results in this research showed lower values for tested structural steel plates, the slip coefficient of A stainless steel material performed better than the W structural steel for each surface condition and at the same temperature range. ABSTRACT This study has evaluated the galvanic coupling corrosion risk between connection bolt materials with ASTM A structural steel, which has recently emerged for the construction of more corrosion-resistant bridges than weathering steel bridges.

The galvanic corrosion risk of using B8 class 2 bolts with A steel was found to be much lower than using galvanized A bolts, but B6 bolt material itself experienced severe crevice and pitting corrosion in both simulated salt solution and salt spray testing.
Galvanic Corrosion Risk Assessment of Bolt Materials in ASTM A Steel Bridges

Highway bridges currently utilize two types of steel, carbon based grades and weathering steel grades. A comprehensive experimental investigation measured galvanic coupling current and potential for samples in cells of aerated salt solution, and the galvanic corrosion risk ranking was validated by visual examinations of bolted steel plates exposed to a salt spray testing chamber.
It’s easy to join and it’s free. Recommendations regarding the slip resistance test method and the methodology for achieving the required surface conditions in slip resistance connection were drawn.
