Latest company news about Corrosion resistance effect of 304 stainless steel pipe

       304 stainless steel pipe is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties!


  Good hot workability for stamping, bending, etc., no heat treatment hardening phenomenon (use temperature -196℃~800℃).


  It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. Has good processing properties and weldability. Plate heat exchanger, bellows, household goods


  (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts, etc. 304 stainless steel is a nationally recognized food-grade stainless steel.


  2. 304 stainless steel pipe is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.!


  A high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, but uses the inherent surface properties of stainless steel. It is used in many applications. A kind of steel, usually called stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance.


  From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen from the intrusion of the steel and acts as a corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.


  Third, most of the requirements for use are to maintain the original appearance of the building for a long time!


  When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted. However, other applications are increasingly seeking structural integrity or impermeability.


  For example, roofs and side walls of industrial buildings. In these applications, the owner’s construction cost may be more important than the aesthetics, and the surface may not be very clean. The effect of using 304 stainless steel pipe in a dry indoor environment is quite good. However, if you want to maintain its appearance outdoors in the countryside and cities, you need to wash it frequently.


  In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusty.
