Corrosion Resistance

Good corrosion resistance in diluted and concentrated acids, fairish in alkalis and halogens, they are resisting in contact with fluorhydric and sulphuric acids and sodium hydroxide, fair resistance in nitric and hydrochloric acids. They are not resisting in contact with molten metals.
