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.

Composition de l'acier inoxydable
L'acier est un alliage de fer et de carbone. Les aciers inoxydables sont des aciers contenant au moins 10,5% de chrome, moins de 1,2% de carbone et d'autres éléments d'alliage. La résistance à la corrosion de l'acier inoxydable et
Les propriétés mécaniques peuvent être encore améliorées par l'ajout d'autres éléments, tels que le nickel, le molybdène, le titane, le niobium, le manganèse, etc.
