WebCorrosion takes place where the oxide layer is breached or under a deposit and is mainly caused by chlorides. Aluminium is extremely corrosion-resistant in very pure water. However, aluminium is very sensitive to galvanic corrosion when coupled with other, nobler, metals such as copper, lead, nickel and tin. WebWhen stainless steel is immersed in acid, the passivation layer may be affected. When this occurs, the layer is eaten away uniformly, and corrosion will occur over the entire surface of the metal. Sulphuric and hydrochloric acids can be particularly aggressive against most stainless steel alloys, especially when in high concentration. park scott lane
