Oxidation

Oxidation is the reaction of metal and oxygen. If the oxide formed is continuous and effective in separating the alloy from the atmosphere, the oxide is protective. However, if the oxide fails to act as a separator, problems with corrosion occur.

Wet corrosion

Wet corrosion occurs in the presence of a liquid containing ions, an electrolyte. Problems with wet corrosion attacks in stainless steels occur in mineral acids, process solutions, seawater and other chloride containing media. Examples of wet corrosion forms are:

Crevice corrosion

Crevice corrosion is regarded as localized corrosion. Problems with crevice corrosion mainly occur in chloride-bearing solutions in combination with a crevice that is wide enough to allow penetration of solutions, but narrow enough to create stagnant conditions. Crevice corrosion is most likely

Galvanic corrosion

Galvanic corrosion can occur when two dissimilar metallic materials are electrically connected in a corrosive environment. The less noble material will corrode. The corrosion rate is strongly dependent on the electric conductivity of the aggressive solution, the difference in corrosion

Selective corrosion

Selective corrosion is observed in alloys in which one part or impurity is clearly less noble than the other parts of the material. The corrosion mechanism implies that the less noble element is removed from the material. A porous material with very low strength and ductility is the result.
