The stainless steel sand castings are the metal casting products in molten stainless steel cast by sand casting process. Stainless steel is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water. Corrosion steel is called acid-resistant steel. Due to the difference in chemical composition between the ordinary stainless steel and acid-resistant steel, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive. The term "stainless steel" not only refers to a single type of stainless steel, but also refers to more than one hundred industrial stainless steels. Each stainless steel developed has good performance in its specific application field.
