The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that are resistant to corrosion by weak media such as air, steam, and water, while acid-resistant steel plates refer to steel plates that are resistant to corrosion by chemically aggressive media such as acids, alkalis, and salts. Stainless steel plate has a history of more than a century since its appearance in the early 20th century.

Carbon steel is a kind of steel with a carbon content between 0.02% and 2% (more than 2% is called cast iron, and less than 0.02% is called wrought iron), and very few other elements. It is also the metal material with the highest output, and the steel with relatively high other components (excluding impurities) is called alloy steel
