Among the metals affected by this type of corrosion are stainless steel, certain magnesium alloys, and the copper-bearing aluminum alloys. Intergranular corrosion occurs in certain grades of stainless steel when the steel is heated, as in welding. Brittleness results, causing the metal to crack near the weld. For this reason, a post-weld heat treatment is needed before reinstalling stainless steel parts that have been welded.
Answer 1: oxygen and carbon in the air :-). Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion.Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids).Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions. There are many methods to prevent corrosion.nswer 1: oxygen and carbon in the air :-). Answer 2: Depends on what type of corrosion you are referring to.
