304 pipes have excellent stainless corrosion resistance and good intergranular corrosion resistance. 304 stainless steel material has strong corrosion resistance in nitric acid below the boiling temperature with a concentration of ≤65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. A high-alloy steel that can resist corrosion in the air or chemical corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, but gives full play to the inherent surface properties of stainless steel. It is a kind of steel used in many aspects and is usually called stainless steel. Representative performance includes 13 chromium steel, 18-8 chromium-nickel steel and other high-alloy steels. From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen that invades the steel and plays a role in corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.

Composición del acero inoxidable
El acero es una aleación de hierro y carbono. Los aceros inoxidables son aceros que contienen al menos 10,5% de cromo, menos de 1,2% de carbono y otros elementos de aleación. La resistencia a la corrosión del acero inoxidable y
Las propiedades mecánicas pueden mejorarse aún más añadiendo otros elementos, como níquel, molibdeno, titanio, niobio, manganeso, etc.
