Recommendations regarding the slip resistance test method and the methodology for achieving the required surface conditions in slip resistance connection were drawn. Just inviting the Stainless folks over to my A thread in the Bridge forum – as very few Bridge folks do much with stainless.

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.
Proceedings of an International Conference Submersible Technology: The mechanical properties of these steels are customarily, but not necessarily, developed by a suitable heat treatment generally referred to as tempering. 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.

Highway bridges currently utilize two types of steel, carbon based grades and weathering steel grades. 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.
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.

Weathering steels were used to attempt to avoid this problem as they form a protective rust corrosion product layer, patina, which can be dense and adherent to steel, during a long-term exposure to the atmosphere. This protective patina can reduce corrosion rate to less than 0. The Eng-Tips staff will check this out and take appropriate action. 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.
