Concrete and stainless steel corrosion issues

WebNov 7, 2024 · The picture above shows a stainless steel which corroded in the heat affected zone a short distance from the weld. This is typical of intergranular corrosion in austenitic stainless steels. This corrosion can be eliminated by using stabilized stainless steels (321 or 347) or by using low-carbon stainless grades (304L or 3I6L). WebIntroduction. Bimetallic corrosion can only occur when two dissimilar metals are in ‘electrical’ contact and are bridged by an electrically conductive liquid. The ‘cell’ produced can result in corrosion to one of the paired metals. This can be an issue when stainless steels are in contact with other metals, depending on the circumstances.
