ABSTRACT This study has evaluated asstm 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.

This abstract is a brief summary of the referenced standard. Abstract The primary aim of this experimental research was to provide information on the slip 1a010 performance of ASTM A stainless steel material and to ascertain if its behaviour is comparable to that of W Structural Steel. A comprehensive experimental investigation measured galvanic coupling current and potential for samples in cells qstm aerated awtm solution, and astn galvanic corrosion risk ranking was validated by visual examinations of bolted steel plates exposed to a salt spray testing chamber.

Use of A steels containing 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.

This specification covers the standard for martensitic stainless steel for various structural, architectural, pressure vessel, and heat-resisting applications.
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.
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.
The material shall undergo heat-treatment by tempering. The Eng-Tips staff will check this out and take appropriate action.

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 aatm corrosion in both simulated salt solution and salt spray testing.
