    The invention is about kitchen utensils, esp. a method for manufacturing rust-proof and wear resistance cast iron pan. It features that machined cast iron pan is treated by gas soft nitriding through inflating ammonia and carbon dioxide. The treated cast iron pan has Cr-coated rust-proof level, thus solving the problem that cast iron pan is easy to rust. Owing to having better thermal stability and anti-oxidability and high crack resisting temp, its service life can be increased by 300% and the advantages that the iron element in cast pan benefits human body is unchanged.
